Inspecting Consumer Whole-Genome Sequencing Data


Posted on June 15, 2023


group picture

As a provider of software, services and training in the area of next generation sequencing (NGS) bioinformatics, we naturally see a lot of sequencing data. The “end users” of our analysis results are typically life science researchers, or biotech- or medical professionals. Recently, a new breed of companies started offering comprehensive DNA sequencing for consumers. For example, they might offer Whole-Genome-Sequencing (WGS), at a reasonable level of coverage, together with a set of potentially interesting analyses, all at an incredibly low price of $300. Therefore, we could not resist the temptation and ordered such a test with the overall goal of checking the amount and quality of data obtained.

What you receive

We decided to order a DNA test from Nebula Genomics, which is one of the largest providers that also offers downloading of the genomic data. After sending back the cheek swab, we had to wait for several weeks until the results were in. You are now able to inspect a range of reports about your genetic traits (simple and complex), ancestry, oral microbiome and genetic variation. A deep-dive discussion of these reports is a little out of scope for what we want to do here, and can be found elsewhere already. Of more immediate interest to us is the raw data itself, which underpins all downstream analysis. We directly went on to the data download section, and were positively surprised about the specific files offered for download. Before ordering, we checked the FAQ, which stated that we will be able to download all data in “BAM format” and “VCF format”, both important for describing sequence alignment characteristics and genetic variant information, respectively. Since BAM files contain alignments to the human reference genome, it was not clear from the FAQ however if the full dataset - including also sequences not aligning to the reference - would be provided.

We now found that we were able to download: 

  • two FASTQ files, containing the all raw sequence reads
  • a CRAM file, containing the alignments to the reference genome in a highly compressed file format (but with the same information as in a BAM file)
  • a VCF file, containing the detected DNA variants
  • Corresponding index files for the CRAM and VCF files which are helpful to increase the performance when working with alignments and variants, respectively

In other words, we are given the complete data in standardized file formats.

It’s worth noting that Nebula Genomics does not provide any QC reports alongside this data. In order to assess the provided data we must analyze it ourselves. So, the following visualizations were created with our own Seamless NGS software and open source tools. Nebula Genomics also does not provide a description of their data analysis workflow, so we will have to reverse engineer some of this information based on the files provided.

Quantity and quality of raw sequencing data

We first looked at the raw sequencing data from the provided FASTQ files:

  • Sequences : 2x 382,683,421
  • Sequence length: 150 bp
  • Total data: 2x 57,4 Gbp
  • File sizes: 2x 52 GiB

The distribution of base qualities is usually one of the most important quality metrics to look at:

We can observe that the medium base quality for all positions in the read sequence averages to a median of 36 (Phred score). When we average the quality for all bases in the read, we see that most sequences have a mean quality score of 37, while some even go up to 39. This amounts to a very good quality by today's standards. According to their FAQ, they employ the MGI DNBSEQ-T7 sequencing machine. Most data from the market leading Illumina sequencing machines will report base qualities that top at 36. Does that mean that the quality here is better than from those common Illumina machines? Not really, since the quality scores reported are essentially estimated by an internal software that has been calibrated by the vendor and any comparison between different sequencing machines should not be based on these numbers. More in-depth studies (e.g. Hak-Min Kim et al) suggest that the raw sequence quality is roughly comparable between those most common platforms. What this means however is that the sequencing laboratory did a good job in operating the sequencing machine.

Alignments

Nebula genomics provides a CRAM file containing the sequences aligned to a reference genome. Let us first find out what tool they used for this step, and what reference. Luckily, the CRAM file itself contains this information: they used the alignment tool minimap2. This is a bit unusual in that bwa-mem is the more widely-used tool, despite being its predecessor, and also the standard tool recommended for the variant analysis pipeline employed later on. However, for most data minimap2 has been shown to provide similar accuracy for variant detection while providing a significant runtime speedup compared to bwa-mem. The output format is quite similar. With the expectation that MGI made some internal tests for how well it works for the MGI DNBSEQ-T7 sequences, this tool is a sensible choice given that they have to handle high data volumes.

The CRAM file also reveals some information regarding what reference genome they have been using. This can be reverse-engineered based on the names and checksums of the chromosomes, for example. This reference version information is of great importance, because if we aim to do any additional analysis using the result files provided by Nebula Genomics Inc., we need to ensure that the same reference genome is used. The reference genome turns out to be a modified version of the Genome Reference Consortium Human Build 38 (GRCh38) using UCSC nomenclature. All information points to the fact that they used Verily's GRCh38 genome, but when comparing it to the downloadable version we found that there are some mismatches in sequence checksums. We asked Nebula for the precise reference genome, but unfortunately they did not provide any answer.

We could however infer that the reference is based on the so-called “analysis set” of hg38. The hg38 contains several features that complicate data analysis (find some details here), and these special versions of the GRCh38 reference genome facilitate a correct use of common read mapping tools with hg38. Notably, the names and coordinates of the 23 chromosomes are the same as the UCSC hg38 assembly, meaning that you should be able to use the VCF file with any hg38-based analysis.

Let’s take a brief look at the alignment statistics:

As expected, most of the reads - 99,4 % to be precise -  could be aligned successfully to the human reference genome. This is a very good number, and it means that there was no major contamination of the sample which can happen, for example if you have a viral infection while taking the mouth swabs. The amount of DNA collected on the swab can also be a bottleneck for sequencing and it's good to see that this wasn't an issue here.

Using the information about known gene locations, we can also look where the reads actually map to:

Human gene sequences consist of introns and exons; the latter are translated into proteins that carry out most functions in the cell. For humans, these “exonic regions” amount to 1-2% of the genome. As you can see, 2% of the reads align to exonic regions, which is the amount we expect. The majority of reads however, align to either intronic or intergenic regions.

Where are the bacterial reads?

One of the reports provided is about the oral microbiome, so the types and abundances of bacteria that were present in your mouth at the time of testing. But how can they know that when they align it only to the human genome? Well, indeed it is not possible to estimate that from the alignments that you get. But. If you look again on our mapping statistics above, you see that 0.6% of the reads do not align with the human genome. And since we are really looking at a lot of data, these 0.6% amount to almost 5 million sequences that we can use for further analysis. Fortunately, Nebula Genomics chose to include the unmapped reads in the CRAM file, which makes it easy to extract them and conduct further microbial analysis of your own! We used the well-known taxonomic classification tool Kraken2 and indeed obtained results very similar to their oral microbiome report.  

Coverage statistics

When it comes to the assessment of sequencing data quality, a key question is: how good is the obtained coverage? Coverage means (link article) how many read sequences “cover” each position in our genome, providing us with a sufficiently large sample size to confidently detect changes. Nebula Genomics promised a coverage of 30x. Let us check if they can fulfill this promise:

The average coverage for the complete genome is 36.1, exceeding the expected value by about 20%. Very nice. We also see that there is some variation between the chromosomes. The biggest outliers are chrX and chrY, which is expected as I have only one of each compared to two of the others… It is a bit unfortunate that the chrY coverage is only 11.9 because this information is valuable for ancestry analysis. I left out the mitochondrial genome (chrM), because with a coverage of 9,620 this is a massive outlier! This is also expected, as each cell contains hundreds to thousands of copies of mtDNA. 

Let us consider that above numbers represent averages over all possible positions in the genome. In practice, the coverage is not uniform but rather looks like this:

Practical coverage

We see that there are coverage hills and valleys, and sometimes the coverage also goes down to 0. The reason is that certain regions of the genome differ in their amenability for sequencing according to their specific sequence content (see here). Unfortunately there is no real way to address this issue, other than by increasing the global level of sequencing depth to ensure that most regions still reach a minimum level of coverage. Ideally, we would like to get a coverage of 20x or more for all positions, because this allows us to confidently detect the germline variants for those positions. We can detect variants also at lower coverages, but with lower confidence. It is likely for this reason that Nebula Genomics offers a global coverage of 30x as a tradeoff.

When it comes to health-related information, often the most directly-relevant regions in the genome are those that eventually get made into proteins and can have a function in the cell. Naturally, it is interesting to look at how the coverage is in this high-priority region. So we did the analysis again, this time limiting ourselves to exonic regions, amounting to about 35 megabases (using a slightly modified set of RefSeq genes, similar to those used for Exome enrichments). Here is how the coverage looks like:

The mean coverage in this region is 32X, and 88% of positions have a coverage above 20x. Unfortunately, about 1 megabase (2.7% of those positions) have such a low coverage that it was not possible to detect variants at all. However, to put this in perspective, also in much more expensive clinical exome NGS kits between 1-2% of positions cannot be called. So this is something that must be expected and can only be resolved with more expensive techniques.

DNA Variants

The last file that we are offered to download contains the detected DNA variants in VCF format. For our sample, the total number was a sweeping 4.84 million variants. About 27k (or 0.6%) of these variants were located in exonic regions. This fraction is significantly less than the fraction of the exonic regions compared to the whole genome. This is entirely expected, since protein-coding exons have a more direct influence on biological processes, and are naturally more conserved due to natural selection. Note that many of the GWAS-related variants are actually outside of exonic regions because of the way these studies are performed.

To detect the variants, Nebula Genomics relied on the GATK HaplotypeCaller as part of the MGIs. HaplotypeCaller is the most widely-used tool for detecting DNA variants from NGS data, and it is completely open source. This is a good choice because it makes it easy to interpret the results and also increases the interoperability with other tools. The whole workflow includes steps for marking duplicates, recalibrating base quality scores and sorting the alignment files, all of which are key steps of a best practices workflow.

Duplication refers to the occurrence of the exact same sequence multiple times. Despite the huge amount of short-read data we are sequencing, the likelihood of such duplicates occurring naturally is in fact very low. High levels of duplication are therefore indicative of issues during sample preparation. Due to the biases introduced by duplicates, high levels can result in reduced confidence in the accuracy of variant calls. Consequently, they are typically excluded from variant detection. We independently assessed the duplication levels, and discovered that there were 24 million (3.2%) duplicate sequences in the data. This aligns with expectations based on other samples of good quality.

Thankfully the VCF already includes a DBsnp identifier. DBsnp is the largest database of human SNPs and having a pointer to the respective database entries simplifies working with the variants a lot. In our case, an identifier was available for about 97% of the detected variants.

Summary

With this we conclude our analysis of the WGS data you can get from consumer genetic testing company Nebula Genomics Inc. The sequencing data comes in sufficient quantities and also in very good quality. Together with the read length of 150 bp, which is good by current short-read sequencing standards, this means that most sequences can be aligned to the human genome, enabling the detection of a high number of DNA variants. Furthermore, Nebula Genomics deserves kudos for not only making available the most relevant files (including the complete raw sequences) but also for using standard tools (and consequently known standard contents) to generate these files. It would be possible to provide some additional QC metrics and analysis results (such as structural variations), and this is partly done by some competitors. However it is totally understandable for Nebula Genomics to not provide them, since in fact you need to be an expert to interpret those results properly - and an expert could also create them for yourself given sufficient computing resources. In summary, I am positively surprised about the great data you can get today for such a small cost. How much actionable advice and learnings you - as an consumer - are able to get from this data by today's knowledge, however, is a different story.

Doctoral Thesis with Honors at ecSeq


Posted on September 07, 2022


University Leipzig

Adam Nunn successfully defended his doctoral thesis on September 5, 2022

On Monday, our PhD student Adam Nunn successfully defended his thesis at the Faculty of Mathematics & Computer Science of the Leipzig University.

The referees all agreed in their decisions: "Summa cum laude" (Passed with highest honors)

Adam has achieved incredible things in the last four years. He has managed the complete server infrastructure of the Marie Skłodowska-Curie Innovative Training Network EpiDiverse, was the main contact person for all 15 PhD students of the project when it came to bioinformatics questions and assembled a new genome in cooperation with University of Minnesota. He also designed, created and maintained several methylation pipelines, which were used by all PhD students for their research.

And here's the thing: He did all of this in parallel to his PhD work.

His PhD thesis was on detecting DNA variants in Bisulfite-Seq data. For this, Adam chose an incredibly simple and clever approach that allowed him to outperform all the tools already on the market. The best inventions don't always have to be the most complicated. Simplicity is where true innovation lies.


During his time as a graduate student, Adam published six papers and was first author on four of these:

  • Nunn A, Otto C, Fasold M, Stadler PF, Langenberger D: 'Manipulating base quality scores enables variant calling from bisulfite sequencing alignments using conventional bayesian approaches', BMC Genomics 23, Article number: 477 (2022)

Dr. Adam Nunn


Adam Nunn started with a BSc in Biological Sciences from University of Portsmouth and a double MSc in Bioinformatics and Biology from Lund University, Sweden. Between the bachelor's and the master's degree, he worked for four years as a lead research scientist for a UK-based company where he focused on developing biological alternatives to chemical pesticides. In 2017 he joined ecSeq Bioinformatics GmbH for his PhD studies. His work is fully funded by the Marie Skłodowska-Curie Innovative Training Network EpiDiverse and in cooperation with Prof. Peter F. Stadler, holder of the bioinformatics chair at Leipzig University. On September 5, 2022, he successfully defended his doctoral thesis at the University of Leipzig. His work was evaluated with a "Summa cum laude" and he will be entitled to use the title "Dr. rer. nat" in the future.

Clever Algorithm - Use standard DNA variant caller on Bisulfite-Seq data


Posted on June 27, 2022


BMCGenomics
Clever Algorithm published in BMC Genomics

Until now, specialised tools are required in order to access DNA variants from bisulfite sequencing data. Experts in the field are often frustrated by the output and performance of the few available variant callers for BS-seq data, to the extent that they tend to re-sequence an additional whole genome DNA-Seq run just to access prominent/trustable tools like GATK (McKenna et al., 2010) or Freebayes (Garrison & Marth, 2012). This results in an expensive outlay in terms of additional cost and labor.

We present a simple bioinformatic pre-processing procedure for mapped BS-Seq data, which makes them usable for all types of DNA-Seq variant callers. This interoperability also produces surprisingly good results with regards to the overall quality and sensitivity. We show that the performance of GATK and Freebayes on BS-Seq data pre-processed by our tool is similarly good as on real DNA-Seq data, with a marked improvement over all tested BS-Seq variant callers. Our approach gives researchers the opportunity to call DNA variants without additional sequencing costs and time-consuming analyses, while using state-of-the-art methods which are continuously optimised through extensive uptake in the community.

Take a look at the simplicity of the method! It is both straightforward to understand for those outside the field and showcases how a small change in perspective can lead to novel and unexpected solutions.

NGS Liquid Biopsy with Genetic Testing Platform 'Seamless NGS'


Posted on September 13, 2021


pathology leipzig

"Lung cancer is among the most frequently diagnosed cancers worldwide. Despite the availability of multiple targeted therapies, these tumors readily develop resistance mutations. To avoid taking invasive biopsies, these mutations can also be detected in liquid biopsies, i.e. blood samples derived from the patient. However, a reliable detection system such as NGS is required and in particular the bioinformatic analysis must be capable of detecting very low frequency variants. Recently, we successfully passed another QuIP round-robin test for the detection of EGFR resistance mutations in tissue as well as liquid biopsies using the Seamless NGS software"

Improving the Sensitivity of Gene Fusion Detection from Archer® FusionPlex® Panels


Posted on August 13, 2021


Illumina NextSeq

Recent studies point to promising new therapeutic options that can be applied in the presence of certain gene fusion events (such as NTRK gene fusions). Diagnostic labs can use RNA sequencing to detect such fusion events. The source material (e.g. tumor tissue) has to be prepared for sequencing using custom-made assays or using commercial assays such as Archer® FusionPlex®.


Given that we recently introduced a new module for detecting fusion events to our Seamless NGS software platform, we were interested in how sensitive our approach is on existing data. But how is it possible to assess the detection level for fusion events? Ideally, there should be an experiment where the fusion events are contained in varying, but previously known, concentrations. One elegant solution: a "dilution series" type of experiment where a solution with the element to study is diluted in another solution at different concentrations.

This is exactly what Dilon et al. did in their publication "Targeted RNA-sequencing for the quantification of measurable residual disease in acute myeloid leukemia". Amongst other things, they diluted ME-1 cell line samples into healthy adult donor peripheral blood mononuclear cells with dilution ratios from 1:10 to 1:100,000. The ME-1 samples contain a known CBFB-MYH11 gene fusion.

Analysis Results

We obtained the raw RNA sequencing data which the authors have shared on a public sequence database. We focused on the ME-1 dilution series that was prepared with the Archer® FusionPlex® Myeloid assay and sequenced with an Illumina miSeq machine.

We then used the new Seamless NGS RNA Fusion workflow to detect fusion events. The algorithm is not limited to known fusion partners or to specific breakpoint locations, enabling the discovery of entirely new fusions. For each fusion event, detailed information is provided that can be used to filter for custom requirements. Besides basic measurements like read support and the fusions probability of being a driver of the oncogenic process, the software provides information about whether or not the fusion is found in databases like TCGA, ChiTaRS. Also, known diseases associations and relevant literature is included. In addition, each fusion event is visualized connecting the gene annotation with the read coverage and the detected breakpoints:

How to measure the abundance of a fusion? The original publication used the “percentage of unique reads spanning the breakpoint and supporting the event divided by the total reads at that locus” as a measure. Since “locus” was not clearly defined, we used a similar metric of “percentage of unique reads spanning the breakpoint and supporting the fusion event divided by the total number of reads at the breakpoint of the CBFB gene”.

The following plot shows these obtained percentages, first as shown in the publication (as computed by the original authors using the Archer® analysis software) and second with Seamless NGS.


Cell Dilution Orginal Study CBFB-MYH11 Seamless NGS CBFB-MYH11
0 41.2% 21.54%
1:101 26.0% 10.91%
1:102 5.1% 2.04%
1:103 0.6% 0.17%
1:104 Not detected 0.01%


Using the software provided with the Archer® assay, they were able to detect the CBFB-MYH11 fusion from dilutions of 1:10 to 1:1,000. However, our approach was able to detect the fusion in dilutions from 1:10 to 1:10,000. This means a 10-fold increased limit of detection for this fusion event.

An alternative way of measuring the abundance of a fusion is to normalize the support against a ubiquitously expressed gene, allowing a comparison between different samples and fusions. The authors are plotting the ratio of target copies/ABL1 copies (log10) against the cell dilution (−log10). They do this both for their custom assay (NIH AML MRD RNA-Seq) (blue) and the Archer® FusionPlex® Myeloid assay (red).

Benchmark

The grey area indicates the cell dilution frequencies in which the mutation could be detected by both methodologies. Note that dilution level 1:105 was not assessed with the FusionPlex assay. When we visualize the results of Seamless NGS similarly, we obtain the following plot:

Benchmark

Again, we see that the abundance of fusion is linearly decreasing with the known dilution of the ME-1 cell lines. As indicated by the gray area, Seamless NGS can detect the CBFB-MYH11 fusion in the Archer® FusionPlex® Myeloid data down to a dilution of 1:104, whereas previous analysis methods from the same data allowed only detection levels of 1:103.

Summary

Fusion analysis with RNA sequencing offers great flexibility and sensitivity for detecting multiple molecular targets in a single assay. Comparing our results with previous results, we were happy to see that Seamless NGS did not only match the sensitivity of the Archer® software but surpasses it by one order of magnitude. This opens up new possibilities for users who would like a software that can flexibly analyze a range of RNA fusion assays from different vendors (Archer®, QiaSeq®, Illumina®, …) without sacrificing accuracy or convenience.

ecSeq at the "Week of the Environment" in the park of Bellevue Palace with German President Frank-Walter Steinmeier

The demand for tires for passenger cars, commercial vehicles, etc., but also for other rubber products, is causing a worldwide increase in demand for natural rubber. A truck tire, for example, contains up to 25 kg of the renewable rubber, whose excellent technical properties are currently not matched by synthetic polymers. To date, natural rubber has been obtained exclusively from the latex of the rubber tree Hevea brasiliensis, which grows in the tropics. In order to meet global demand in the medium term without tropical virgin forests having to make way for additional rubber plantations, alternative sources of natural rubber are needed. Russian dandelion Taraxacum koksaghyz, which can also be grown in temperate climates, produces a qualitatively comparable milky sap. In perspective, it is capable of diversifying rubber production and, in the process, preventing the depletion of endangered rainforests. However, Russian dandelion also offers the opportunity to increase the diversity of crops in domestic fields.

Communicate Knowledge - Comprehensive benchmarking of software for mapping whole genome bisulfite data: from read alignment to DNA methylation analysis


Whole genome bisulfite sequencing is currently at the forefront of epigenetic analysis, facilitating the nucleotide-level resolution of 5-methylcytosine (5mC) on a genome-wide scale. Specialized software have been developed to accommodate the unique difficulties in aligning such sequencing reads to a given reference, building on the knowledge acquired from model organisms such as human, or Arabidopsis thaliana. As the field of epigenetics expands its purview to non-model plant species, new challenges arise which bring into question the suitability of previously established tools. Herein, nine short-read aligners are evaluated: Bismark, BS-Seeker2, BSMAP, BWA-meth, ERNE-BS5, GEM3, GSNAP, Last and segemehl. Precision-recall of simulated alignments, in comparison to real sequencing data obtained from three natural accessions, reveals on-balance that BWA-meth and BSMAP are able to make the best use of the data during mapping. The influence of difficult-to-map regions, characterized by deviations in sequencing depth over repeat annotations, is evaluated in terms of the mean absolute deviation of the resulting methylation calls in comparison to a realistic methylome. Downstream methylation analysis is responsive to the handling of multi-mapping reads relative to mapping quality (MAPQ), and potentially susceptible to bias arising from the increased sequence complexity of densely methylated reads.

Are Online Trainings for NGS Data Analysis as Effective as In-person Workshops?


Posted on November 06, 2020


Participating in a in-person workshop where everyone is in the same room and a trainer is present definitely has its advantages. Personal discussions and meetings are wonderful experiences. But especially now, during the Corona pandemic and the resulting restrictions, this is not always possible.

Now often the question arises 'Are online courses an alternative?'

The truth is that many of the participants are amazed at the value they get from our online courses.


Here are three powerful reasons to give it a try:

  1. Nothing is easier than attending an online course.
    What could be easier than taking an online course? You can be on a different continent and participate in one of our courses online for several days. All you need is Internet access and a headset.
  2. It is cost-effective.
    With an online course you save time and money. You don't have to plan your travel and you don't have to worry about the logistics of accommodation. Likewise, you will not have any lost days of arrival and departure.
  3. The quality is very high.
    Our experts have created online learning plans that are as extensive as workshops that are held in person and offer plenty of opportunity for interaction. Same quality - just a different format.

What is special about ecSeq's online workshops?

We have invested a lot of time and effort to keep the differences between the online courses and the classroom courses as small as possible.

The theoretical part

Besides the typical webinar style where the trainer talks and shows things with the mouse on a shared slide, we also use traditional teaching methods. Here the trainer is filmed in front of the screen with the slides and can therefore teach more freely. Sometimes you simply need both hands to explain difficult procedures. If something needs to be drawn for an explanation, the screen of an iPad is shared, on which the trainer can write and draw properly. As you can see, we use all modern possibilities to get the most out of the online course. You will be amazed how effective this works.

Online_Workshops

The hands-on part

The biggest differences between our online courses and classroom courses can probably be found in the practical part. Here our developers have come up with something very special to make the experience of the practical part perfect. We give each participant access to a cloud computer on which they can perform the exercises. Using a common web browser, you can log on to this cloud computer and perform the exercises in a browser-based Linux terminal. You do not need to install anything for this.

And now comes the best:
Our trainers can look at your terminal in real time and even help you interactively. This is really like classroom training, where the trainers also walk through the rows and offer their help.

Note: The assistent can only see your in-browser terminal window but nothing else and also do not have any access to your computer.

Online_Workshops

The social interaction

This is probably the part where you understandably have the most disadvantages compared to a classroom course. You can't ask your table neighbor for help, you can't have a chat during the breaks and there are no networking events, such as the common dinner.

Nevertheless, we try to make the best out of the situation. In addition to a joint introduction round, in which everyone introduces themselves briefly, we use all possible communication channels to make the course as interactive as possible. Participants can raise their hands, unlock their microphones if they have questions, or communicate with each other in the chat. Each time we are surprised how much interaction is possible. Even short discussions between several participants are not unusual.

Online_Workshops

Summary

Of course, learning in an online course is different from learning in class. Nevertheless, during our first online courses we have noticed that the quality remains consistently high and is in no way less than that of a classroom course. The limitations of social interaction can be minimized by the technical possibilities. The financial and time advantages are and remain without question. The participants of our previous courses have given us only positive feedback, which shows us that online courses are a good replacement for classroom courses.

Nevertheless, we hope that the pandemic will soon come to an end and that we will again be able to face the participants of our courses directly. Until then, we hope that you all stay healthy!

Emmanuelle Charpentier

Huge congratulations to Emmanuelle Charpentier on the Nobel Prize

After we conducted an on-site course in the laboratory of Emmanuelle Charpentier (then at the Helmholtz Centre for Infection Research in Braunschweig) in 2014 to train her PhD students in the application of NGS data analysis, we have made our software Seamless NGS available to her research group. Emmanuelle is an extremely intelligent and determined woman who, despite her incredible success, is neither arrogant nor stuck-up. There are few successful scientists who have kept their feet on the ground and always talk to their conversation partner at eye level.

"I congratulate Emmanuelle on winning the Nobel Prize and wish her continued success for the future. Science needs exceptional people like her, who not only conduct outstanding research but are also able to communicate this to the outside world. Emmanuelle can do both. I am already looking forward to future projects with her." David Langenberger, CEO of ecSeq Bioinformatics GmbH

Save time and money through improved onboarding of your NGS data scientists


Posted on September 14, 2020


On-Site_Workshops
Better training significantly reduces onboarding time for new hires

Hiring a suitable biologist or bioinformatician for sequencing data analysis takes lot of effort. Even if you are lucky and find the right talent, significant time is needed for on-the-job training. Your new team member needs time for learning before meaningful work results can be archived. This learning curve means that it could take weeks or even months for your new hiring to start working on his/her project.

The onboarding process is all about making employees, PhD students or Postdocs feel valued, providing them with the training and tools they need to succeed, and building a relationship with the workplace.

Employess with little or non onboarding often feel that they have to sink or swim alone, and are more likely to jump off the boat at the first opportunity. Since onboarding is the first real interaction of new team members with your company or institute, leveraging the experience is critical to avoid losing them.

We at ecSeq offer special NGS data analysis traingings, enabling your team members to quickly and purposefully enter this exciting field of work. With our training courses, the onboarding period can be reduced from several months to a few weeks. Starting with the basics (notations, methods, general understanding), we illustrate important error sources and slowly introduce participants to the Linux operating system. We show which tools can be used, how they have to be used and how one can interpret the results correctly. After our workshops, your new employees will be able to perform initial NGS data analyses independently and understand important technical NGS publications in detail.

Interested?

Several times a year, we organize introductory and advanced public courses on selected topics in next-generation sequencing data analysis.

Or do you want our trainers to come to you? Our on-site courses are very popular with companies or graduate schools from academic institutes or universities.

Whole-Exome Analysis on a Mainstream Desktop PC


Posted on September 12, 2020


Analysing NGS data usually is the domain of power compute servers or High-Performance Clusters, as it typically has massive volume and requires a lot of data crunching. However, the power of available CPUs is increasing, and now there are faster processors with more cores available on the market at competitive prices. This applies not only to the sector of the server “workhorses” but also to the sector of “standard” Desktop PCs. This sector is characterized by commodity hardware that is produced in high volumes and can be bought at affordable prices. While this kind of PC used to have just a single core, it is today possible to buy Desktop CPUs with as many as 16 cores.

Given the price premium that is necessary to enter the high-performance server sector, the question arises: why not use commodity hardware for NGS data analysis? So we started an experiment: how feasible is it to do a resource-intensive whole-exome sequencing (WES) analysis on a modern Desktop PC.

Hardware setup for WES analysis

We went on to assemble a suitable new computer with current hardware. We went for a 12-core AMD Ryzen 3900X CPU. This processor was released in 2019 and offers great performance. We then included 32 GB of RAM as well as a fast M2 SSD hard drive to make it suitable for the computation of NGS data. The total costs of this system were less than 1500 Euro.

We compare this to our 5-year old HPC unit that boasted an Intel Xeon processor with a total of 40 CPU cores. More CPU cores means that more computations can be conducted in parallel. The analysis will be much faster as long as the software is able to effectively make use of this parallelization. The HPC unit contained a RAID storage system with around 40 TB hard drives. At the time of buying this system had a price tag of around 12.000 Euro. So this is 800% the price of our new system.

As example data we took a full sequencing run of an Illumina NextSeq 500 that contained 16 whole-exome samples. Each was sequenced to an expected ~60x coverage using a Twist Bioscience Human Exome Kit with a target size of 36 Megabases. The sequencing run has a total sequencing depth of 100.4 Gigabases.

We analysed this data using the Seamless NGS software. Since our focus is to assess the performance gains due to hardware, not due to software, we used a (moderately optimized) standard analysis workflow relying on widely used NGS tools (e.g. BWA alignment). We previously confirmed that this approach for DNA variant detection meets our expectations regarding sensitivity (>0.99), specificity (>0.98) and reproducibility. Our analysis includes all auxiliary steps such as preprocessing, quality control and DNA variant annotation. Even though it is possible to perform Copy-Number Variation (CNV) analysis with Seamless NGS, it was excluded from the runtime analysis.

We were also interested whether there is a significant difference in the runtime between Linux and Windows, so we installed both operating systems on the new computer. Seamless NGS runs on both of these, so we could use that for comparison. For technical reasons we could not install Windows on our HPC.

What were our initial expectations before running the experiment? Our HPC unit is quite powerful. With 12 vs 40 CPU cores, it has more than 3 times as many physical processors available for challenging computations. On the other hand we have seen considerable improvements of computer hardware in the last years, including the availability of affordable SSD drives as well as the release of new processors with higher per-core performance. So we think that it is entirely possible that the NGS analysis performance of the new system is on par with our HPC unit.

WES runtime comparison results

Before looking at the performance of the different systems, we need to establish that we obtain comparable analysis results in all the test cases. To this end, we compare several important QC measures - the number of detected variants, alignment rate, mean coverage - across the different systems. We find that these numbers are absolutely identical - so we can go on.

Let us first look at the runtime on the High-Performance Cluster (on Linux). We will visualize the time required for the analysis separated by individual analysis steps. We here omit small steps that take only a few seconds and also group these steps into broader categories (e.g. Quality Control) for good oversight. Let’s take a look at the resulting Gantt chart:

The total runtime is about 21 hours - this is slightly below 2 hours per sample. This is not a bad time, considering that all necessary steps (including annotation) are already included in this analysis. Most of that time is spent with the alignment, variant calling and preprocessing raw reads.

Next, let's take a look at the runtime of the same analysis on our new 1500-Euro computer, running Linux:

Wow! The total runtime on this is about 10h, or about 50 minutes per sample. This result beat our wildest expectations. Yes, we expected that hardware improvements would lead to a strong improvement on a per-core basis. After all, hardware manufacturers are constantly innovating and competing hard over every performance gain. We did not expect that the 12-cores would in fact beat the 38-core HPC by THAT much. From this cursory analysis it is not entirely clear to us what factor(s) are responsible for these performance gains, but likely it will be a combination of increased CPU speeds, CPU processing efficiency, storage speed and mainboard bus throughput.

Now let’s take a look on what happens when we use the same machine, with the same data and analysis, but switch the operating system from Linux to Windows 10:

In this case, the runtime is slightly higher on Windows compared to that on Linux on the same machine. The difference however is not substantial - each sample takes about 55 minutes. Most of the difference takes place in the alignment step.

Finally, let us look at the total runtime differences:

Outlook

Are there faster ways to analyse Whole-Exomes, Whole-Genomes or Clinical Exomes? Absolutely. You could replace standard tools with high-performant software more suited to the specific data. You could employ dedicated computer hardware such as Field Programmable Gate Arrays (FPGAs) or Graphical Processing Units (GPUs). In fact, it is possible to purchase commercial systems that combine some of these techniques to bring down the computation time to as low as 8 minutes per exome from reads to DNA variants. However, the goal of this post was a different one: to show how far you can go today without a big investment.

The results of our test really surprised us: it is possible to easily analyse two NextSeq 500 runs comprising 24 Whole Exomes in a single day on a ‘normal’ Desktop PC. This means that even such a low-cost system is able to analyse more than 8000 exomes per year! We expect that with a bit more optimization, significantly higher numbers will be possible - on a single machine. Most software tools will also allow you to combine several machines. Does this mean it is time to rethink the hardware requirements needed for NGS data analysis, including Whole-Exome Sequencing?

Transferring patient's genetic testing data to the cloud: 5 myths


Posted on September 09, 2020


dandelion

We often get the question: how safe is it to transfer patient’s genomic data to the cloud? By this most people refer to the transfer of their NGS-based patient data to external web-based services (e.g. Illumina Basespace) that run on the public cloud of other third-party providers (e.g. Amazon AWS).

Of course, patient genetic data security should be a top priority. New sequencing technologies create large data volumes for each patient, and often small labs and hospitals assume that they cannot cope with the required increase in computational resources, leaving the cloud the only option. After all, cloud-based solutions are good for cases where varying amounts of data must be processed flexibly. But it is also true that a patient’s genetic testing data has a different privacy value compared to for example videos, music, images or other large data. Genetic testing data contains highly personal information, including health, behavioural and biometric information, and is an even more unique marker than a fingerprint. A DNA data breach is much worse than a credit card breach.

DNA fingerprint

With that in mind, let us address the following misconceptions and myths we often hear.

Myth 1: "But I am using anonymous IDs instead of patient names”

A good practice in clinical diagnostics is the use of anonymized patient identifiers instead of real names. In the age of genomics, however, this is not sufficient anymore. Everybody working in genetics should internalize this: there is no effective way to anonymize genetic data! It is absolutely possible to infer the person from any sufficiently large genetic data, because the data is intrinsically identifying.

For this very reason, genetic data is considered Personally Identifiable Information (PII) according to Europe’s privacy law GDPR. Other PII includes fingerprints, real names, identification numbers, location data and online identifiers (e.g. IP addresses). In addition, because genetic data can reveal additional information about a person, such as ethnicity, it is explicitly part of “special categories of personal data” according to Article 9 of the GDPR. That means that the GDPR puts in tight regulations for the handling of genetic data itself. These include intense security requirements, limited data access guidelines and non-trivial obtaining of legally watertight consent. Any sloppiness with or even leakage of genetic data therefore comes not only with a loss of reputation but also potentially large GDPR-related compensations.

Myth 2: "But the IT security of vendor X surely is better than ours"

Cloud server

It might be true that some vendor X has a great IT security team and therefore is able to secure their servers very well. Yet, your data still is likely less secure. Consider that the total risk for data leakage is not the risk of the weakest part; it is the combined risk of all involved parties. Some IT specialists describe cloud as “just someone else’s computer”. In practice several parties (e.g. the web service provider, the infrastructure provider, third-party service providers) potentially have access to the computing and storage devices that contain patient data. Obviously, the more parties have access to data, the higher the “attack surface” which describes the potential for data leaks. This total risk should be minimized.

A leakage can occur at any involved party, be it your lab, a service vendor, additional cloud vendors etc. Consequently, you should be aware of and audit the security of all involved parties. There are vendors that perhaps you don’t even think of in the first place, such as the payment processing vendor that is linked to a 2019 breach of patient records of more than 19M american patients.

When a leakage occurs, it is usually difficult to determine who is really at fault, as can be seen in the case of AWS and Capital One. The legal consequences in such a case are difficult to assess and insurance companies will only compensate when it is clearly established who has committed a mistake. But, no matter who is at fault, the reputation of involved diagnostic labs will be ruined.

As a final point, if any malicious actor would be able to obtain access to your labs computer infrastructure, it is likely that they will be able to use this to access information actually available via external providers or services. So total risk should always include the local lab security.

Myth 3: "But the data is transferred encrypted, e.g. using a VPN"

In order for the data to be analysed at external vendors, they must have complete access to the raw, unencrypted data. Nobody can do meaningful data analyses with encrypted data. To display patient reports to you, those reports must be stored at the vendors database. When you use a VPN to work with the external service over the internet, the data is only encrypted on the way from your computer to the service provider. Actually, a similar kind of data “transport encryption” is activated on nearly every website you visit by default using SSL (see the lock symbol in your browser bar). This means that any additional communication security between your web browser and service provider is mainly window dressing, with no real security benefit.

Myth 4: "But our vendor is certified (e.g. HIPAA or medical device)"

There are many certifications that can be applied in the scope of genetic data processing. Many of them do not specifically address IT security, or do so only at a very basic level. Certification guidelines are often not able to cope with the speed of development, for example the massive increase in genomic data that is now possible with the newest generation of sequencing machines. As a case in point, it is known that the “HIPAA does not consider genome sequences as identifying information that has to be removed under the Safe Harbor Method for deidentification”. With the new data amounts, genomic data cannot be considered deidentifiable anymore. You are responsible for establishing appropriate security levels and performing due diligence rather than relying on maybe unrelated or obsolete certifications.

Myth 5: “But I need the scalability of the cloud for NGS analyses”

The major benefit of public clouds is that, in some minutes, you will be able to use dozens of computers that can do work for you. This is a highly appreciated feature, in particular for research making use of large data volumes over short analysis “peaks”. From our experience, most routine labs are able to handle large data volumes and sequencing throughout themselves. We have seen labs with dozens of sequencers that process their data in-house easily, and probably have significant cost savings with respect to cloud computing. Often internal computer infrastructure for workstations, LIMS, medical records servers are maintained anyway. Also, you would perhaps be surprised what a single server with optimized software can compute: 30 exomes in a day are doable.

The fingerprint analogy

Fingerprints are, like genetic data, personally identifying information. Nowadays many phones include a fingerprint sensor making access to your mobile phone both secure and convenient. For this feature, your phone must be able to store and analyse fingerprints. How does it secure your fingerprint from potentially malicious apps installed on your phone? Does it maybe even send you fingerprint for backup to the cloud?

It turns out, phone developers took these concerns seriously and worked out a secure way to deal with fingerprints. Android phones are required to use a special isolated area on the phone, called TEE, to store and analyse fingerprint data. This often is a separate CPU with its own memory and own operating system, completely isolated from the rest of the phone’s system. When you register a fingerprint on your phone, the scan from the sensor is sent to the TEE which creates validation data and encrypted fingerprint data. With this encryption, it is not possible to make sense of this data even if some app would manage to get hold of it. Hence there is no way that the fingerprint ever leaves the phone. All the validations are done in the TEE, and only cryptographic proofs of the validation are delivered.

DNA fingerprint

Summary

A lot of misbeliefs can be heard in the area of genomic data security, in particular in the field of cloud services. Cloud computing brings convenience: customers don't need to install software and can outsource IT services and infrastructure. But there might be cases where risks, data privacy regulations and practical considerations outweigh this convenience. The sensitive information intrinsic to genetic data in the genomics age is often overlooked. If you would hesitate transferring customer fingerprints, patient names and medical reports to the cloud, then you should make no exception to modern genetic testing data.

NGS Data Analysis Workshop, July 2020


Posted on July 27, 2020


btS Logo

Our course “Next-Generation Sequencing Data Analysis: A Practical Introduction” in Munich last week was a great event despite the Covid-19 pandemic and the corresponding limitations and hygiene restrictions. The 8 participants had a perfect supervision key and were able to get a first insight into the world of NGS data analysis during the three days. The gained knowledge will allow the researchers to start their own analyses and it will help them to discuss their bioinformatics problems or questions with bioinformaticians on an almost equal level.


UPCOMING NGS DATA ANALYSIS WORKSHOPS:



Improving the Sensitivity of Gene Fusion Detection from Archer® FusionPlex® Panels


Posted on March 19, 2020


Illumina NextSeq

Recent studies point to promising new therapeutic options that can be applied in the presence of certain gene fusion events (such as NTRK gene fusions). Diagnostic labs can use RNA sequencing to detect such fusion events. The source material (e.g. tumor tissue) has to be prepared for sequencing using custom-made assays or using commercial assays such as Archer® FusionPlex®.


Given that we recently introduced a new module for detecting fusion events to our Seamless NGS software platform, we were interested in how sensitive our approach is on existing data. But how is it possible to assess the detection level for fusion events? Ideally, there should be an experiment where the fusion events are contained in varying, but previously known, concentrations. One elegant solution: a "dilution series" type of experiment where a solution with the element to study is diluted in another solution at different concentrations.

This is exactly what Dilon et al. did in their publication "Targeted RNA-sequencing for the quantification of measurable residual disease in acute myeloid leukemia". Amongst other things, they diluted ME-1 cell line samples into healthy adult donor peripheral blood mononuclear cells with dilution ratios from 1:10 to 1:100,000. The ME-1 samples contain a known CBFB-MYH11 gene fusion.

Analysis Results

We obtained the raw RNA sequencing data which the authors have shared on a public sequence database. We focused on the ME-1 dilution series that was prepared with the Archer® FusionPlex® Myeloid assay and sequenced with an Illumina miSeq machine.

We then used the new Seamless NGS RNA Fusion workflow to detect fusion events. The algorithm is not limited to known fusion partners or to specific breakpoint locations, enabling the discovery of entirely new fusions. For each fusion event, detailed information is provided that can be used to filter for custom requirements. Besides basic measurements like read support and the fusions probability of being a driver of the oncogenic process, the software provides information about whether or not the fusion is found in databases like TCGA, ChiTaRS. Also, known diseases associations and relevant literature is included. In addition, each fusion event is visualized connecting the gene annotation with the read coverage and the detected breakpoints:

How to measure the abundance of a fusion? The original publication used the “percentage of unique reads spanning the breakpoint and supporting the event divided by the total reads at that locus” as a measure. Since “locus” was not clearly defined, we used a similar metric of “percentage of unique reads spanning the breakpoint and supporting the fusion event divided by the total number of reads at the breakpoint of the CBFB gene”.

The following plot shows these obtained percentages, first as shown in the publication (as computed by the original authors using the Archer® analysis software) and second with Seamless NGS.


Cell Dilution Orginal Study CBFB-MYH11 Seamless NGS CBFB-MYH11
0 41.2% 21.54%
1:101 26.0% 10.91%
1:102 5.1% 2.04%
1:103 0.6% 0.17%
1:104 Not detected 0.01%


Using the software provided with the Archer® assay, they were able to detect the CBFB-MYH11 fusion from dilutions of 1:10 to 1:1,000. However, our approach was able to detect the fusion in dilutions from 1:10 to 1:10,000. This means a 10-fold increased limit of detection for this fusion event.

An alternative way of measuring the abundance of a fusion is to normalize the support against a ubiquitously expressed gene, allowing a comparison between different samples and fusions. The authors are plotting the ratio of target copies/ABL1 copies (log10) against the cell dilution (−log10). They do this both for their custom assay (NIH AML MRD RNA-Seq) (blue) and the Archer® FusionPlex® Myeloid assay (red).

Benchmark

The grey area indicates the cell dilution frequencies in which the mutation could be detected by both methodologies. Note that dilution level 1:105 was not assessed with the FusionPlex assay. When we visualize the results of Seamless NGS similarly, we obtain the following plot:

Benchmark

Again, we see that the abundance of fusion is linearly decreasing with the known dilution of the ME-1 cell lines. As indicated by the gray area, Seamless NGS can detect the CBFB-MYH11 fusion in the Archer® FusionPlex® Myeloid data down to a dilution of 1:104, whereas previous analysis methods from the same data allowed only detection levels of 1:103.

Summary

Fusion analysis with RNA sequencing offers great flexibility and sensitivity for detecting multiple molecular targets in a single assay. Comparing our results with previous results, we were happy to see that Seamless NGS did not only match the sensitivity of the Archer® software but surpasses it by one order of magnitude. This opens up new possibilities for users who would like a software that can flexibly analyze a range of RNA fusion assays from different vendors (Archer®, QiaSeq®, Illumina®, …) without sacrificing accuracy or convenience.

Rubber from russian dandelions


Posted on January 16, 2020


dandelion

Joint project with Fraunhofer IME

Russian dandelion (Taraxacum koksaghyz) produces a rubber of comparable quality to the tropical rubber tree. It also grows in temperate climates and is thus able to expand natural rubber production to our regions. The cultivation of dandelion also offers the opportunity to increase the diversity of cultivation on domestic fields.

Russian dandelion is a close relative of our native dandelion. It enriches in its roots a whitish, sticky, rubbery milky sap, the so-called latex. Since dandelions are only of limited use as a wild plant for agricultural production, plant breeders clarify the physiology of rubber synthesis and develop suitable varieties for successful industrialization. These should be characterized by high root yields, latex content and resistance to plant diseases, pests and drought. And, like sugarbeet, the roots must be easy to clear and as clean as possible and then easy to store and process.

To achieve this, together with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME, ESKUSA GmbH and hortilab, ecSeq Bioinformatics GmbH generated a high-resolution genetic map of Russian dandelion.

This is used to achieve the following breeding objectives:

  • Stabilize yields and, in the long term, increase them to approximately one ton of natural rubber per hectare per year
  • Optimise root geometry to minimise soil attachment, contamination and losses during harvest
  • Improve drought tolerance
  • Increase resistance to disease

Dr. Langenberger on analyzing Qiagen's QiaSeq DNA Panels using Seamless NGS Software


Posted on August 19, 2019


Commercial library preparation kits for NGS instruments are getting increasingly complex in order to obtain high sensitivity while reducing bias and errors immanent in current sequencing technology. One approach offered by Qiagen Inc. in their QiaSeq Targeted DNA Panels is using a combination of single primer extension and molecular barcodes.

In March, Dr. David Langenberger, CEO of ecSeq Bioinformatics, chaired the 'NGS & NGS Data Analysis' session at the '9th Gene Quantification Event qPCR dPCR & NGS 2019'. He also held a talk with the title "Tiled Amplicons Panels in NGS-Based Genetic Testing" where he spoke about the challenges involved analyzing such panels. An active discussion was carried about the question whether anyone but experiences NGS bioinformaticians will be able to use standard software or build in-house pipelines for complex panels. Dr. Langenberger also presented Seamless NGS as push-button software solution with excellent support for QiaSeq Targeted Panels.

For more information on the software solution please visit Seamless NGS Website or download the brochure.

Privacy implications of genetic data sharing


Posted on July 08, 2019


Data is the new oil has been the slogan of recent years, explaining the tremendous rise in power and the data hunger of tech companies such as Facebook. Emails, contacts, social interactions, online activity, payments, hobbies, interests, location profiles - everything is collected. However there are increasing concerns with the current practices of handling these vast treasures of data, particularly with third-party sharing, its exploitation for unethical purposes and leakage of not sufficiently secured data. These practices leave customers with uncomfortable feelings and spurn initiatives advocating for more privacy and security regulations.

Meanwhile, consumer genetic testing companies are advertising a range of low-priced products offering personalised health or ancestry information from nothing more than a bit of your saliva. Many are wondering: wouldn't one of those kits be a good present for friends, relatives or themselves? Working in the Bio-IT field, I feel that many are underestimating the amount of highly personal information that can be gained from genetic testing, and are therefore overlooking the consequences of sharing their genetic data with these companies. With that in mind, let's take a look at what genetic information can reveal about you.


Genetic data as unique human identifier

Due to the imperfections of biology, no two humans have identical DNA. Even identical twins that start with the same DNA from a single fertilized egg will accumulate mutations over time. Some occur so early in embryonic development that the majority of cells will inherit them, leading to small but detectable differences in their genetic code (1). DNA therefore is a durable and unique marker of human identity, and much more precise than other biometric markers such as fingerprints.

Genetic data can reveal your identity using databases

There exist various databases collecting genomics information from consumer genetic tests. As shown in a 2018 study your genetic data can be used to reveal your identity with impressive accuracy. As of the time of the study, it was estimated that 60% of people with European descendancy can be pinpointed to a third-cousin or closer match based on existing data. With more and more genomic data becoming available, these numbers can grow rapidly.

Figure 1: A hypothetical family tree showing the reach of public genetic databases. In this example, one of your third cousins, who shares the same great-grandparent as you, posts their test results and makes you identifiable. Figure by Aparna Nathan (article)

Already, these techniques are being increasingly utilised by law enforcement. In May 2019, big discussions were sparked by a case of violent assault where DNA was uploaded to a database for comparison with available genetic data, leading to the identification of a suspect. Critics fear that this technique will be increasingly used for less serious crimes, particularly as there is astonishingly little oversight regarding your own right to genetic privacy if you are identified in this manner. The success of this technique shows: your genetic data can never be anonymous.

Genetic data provides phenotypic information

DNA phenotyping is the task of predicting a person’s physical features using only genetic data. This a very active research area. It is already possible to determine eye color, hair color and skin color with high confidence. A 2017 study successfully used genomic data to predict facial structure, voice, biological age, height, weight and other human physical traits. There are already companies that commercially offer to predict the physical appearance of an unknown person from only their DNA, as obtained for example from a tiny bit of saliva on a cigarette butt.

Figure 2: Actual (left) and predicted from DNA (right) faces (from this study).

When asked, people usually underestimate how much of these physical traits are due to genetic factors versus environment. Heritability is the scientific term describing how much of a trait, for example differences in body height, can be attributed solely to genetic differences. The heritability of eye color for instance is 95%, so eye color could nearly completely be determined by your genes. The heritability for body weight (!) and height is 80% and 70%, respectively. Consequently, it can be expected that advances in DNA phenotyping will enable determination of more and more accurate, biometric information from genetic data in the near future.

Genetic data contains behavioural information

A long-standing question, not only among behavioural scientists, is how much of our personal character is determined by genetics and how much is due to our environment (e.g. education). There are an increasing number of studies suggesting that the majority of psychological differences can be attributed to genetic factors. As psychologist Robert Plomin writes in his 2018 book “Blueprint”:

In summary, parents matter, schools matter, and life experiences matter, but they don’t make a difference in shaping who we are. DNA is the only thing that makes a substantial systemic difference, accounting for 50 percent of the variance in psychological traits. The rest comes down to chance environmental experiences that do not have long-term effects.

Some of the traits that were already examined for heritability include school achievement (60%), verbal ability (60%), spatial ability (70%) and ability to remember faces (60%). All of these attributes are encoded in our genetic data. As with phenotypic information, it is therefore increasingly possible to predict a person's behavioural traits based on only DNA.

Genetic data provides health information

Some hereditary diseases such as cystic fibrosis, sickle cell disease, and haemophilia are related to abnormalities in a single gene, and can be identified by reading out your DNA. Many other disorders are related to multiple genes in combination with environmental factors. These are known as complex disorders.

A relatively new development is the possibility to determine an individual's risk for common complex disorders like coronary artery disease, atrial fibrillation and type-2 diabetes. So-called polygenic risk scores now make it possible to compute a significant fraction of increased risk for these diseases. This is done by combining multiple genetic markers into a single score to predict lifetime outcomes. For example a polygenic risk score could be established for the onset of the severe mental illness schizophrenia (80% heritability). These scores can be helpful information for doctors when considering treatment options. However, information about disabilities or mental health should deserve the highest protection. Think about how employers, insurance or finance institutions could predicate their actions if it were known that an onset of schizophrenia is likely. As of today, no company who has genetic data is obliged to tell you about the findings and judgements from it.

Genetic data contains information about your relatives as well

Following the laws of inheritance your parents, siblings and kids share roughly half of their genetic information with you. Other relatives also share significant parts: you share 12.5% of DNA with your cousin, and about 0.8% with a third-cousin. Therefore sharing your genetic data always means sharing information about your relatives. It means that it cannot be avoided that genetics testing companies are getting more information than they imply, and you should always consider the consequences for your relatives’ interests and rights.

Awareness for genetic privacy

It cannot be overstated: intensely private and personal information - in a surprising breadth and depth - can be gained from genetic data. It could be summarised like this in the oversimplified formula:

Genetic data = fingerprint + passport + appearance + behaviour + health information

So who shall you trust with the handling of your genetic data? We have become more and more accustomed to events of "we are sorry that we have to report a cybersecurity incident", from even the most technologically potent firms. So is it worth it to demand higher security standards for genetic testing companies? Given the power of genetic data, I think higher security requirements are a must. Leaking of material information is bad, but at least you can react. You can change passwords, emails, credit card numbers, in emergency even addresses. But you cannot change your genetic code.

In June 2019 it became known that personal, financial and medical data of the two largest american genetic testing companies, LabCorp and Quest Diagnostics, had been leaked, totalling to 20M patients. Both companies shared this data with a third-party provider which had been breached. It is a simple truth: the more parties with access to sensitive data, the more likely eventual data leakage becomes. Furthermore, consumer genetic testing companies tend to have a second business as data brokers, selling your genetic data to third parties.

It is a valid demand for consumers and patients to have a right for genetic data privacy and security. The GDPR explicitly includes “genetic information” in their data privacy regulation, which is a step in the right direction, but greater awareness about what we are giving away with this kind of data is of utmost pertinence in this fast-growing market. Not every company has data security as their top priority, so consumers need to maintain their own due diligence to make sure there is sufficient trust when sharing the deep information inherent in genetic data.

Footnotes:

(1) Consumer genetic tests will typically read out only the highly-variable sites (polymorphisms) instead of the complete DNA. For anyone except identical twins these tests will give significant differences. Some information might only be extracted from more comprehensive “genomic” data. But due to the growing possibilities for imputation, i.e. increasing the information from limited available data using the data from others, the partial genetic data from consumer genetic tests is often sufficient.

Diagnostic test for risk assessment of arteriosclerosis


Posted on June 24, 2019


dandelion

R&D cooperation project - Diagnostic tests for risk assessment of arteriosclerosis and its sequelae

Arteriosclerosis is probably the most common disease worldwide. With increasing age, the number of patients with significant arteriosclerotic changes increases, and it can be assumed that practically every patient over 80 years of age has at least one form of this vascular disease. The age distribution in the western world will lead to a further increase in arteriosclerotic systemic diseases. In Germany, arteriosclerosis and its complications led to 3500 days of inpatient hospitalisation per 100,000 inhabitants in 2015.

Typical secondary diseases of arteriosclerosis with considerable epidemiological and economic significance are myocardial infarction, stroke, aortic aneurysms caused by arteriosclerosis, peripheral arterial occlusive disease and chronic renal insufficiency.

Arteriosclerosis as a cause of cardiovascular disease is currently responsible for most deaths and illnesses in industrial societies. If the diagnosis is made in good time, arteriosclerosis can be treated (with medication, change of behaviour) and the majority of its sequelae can be prevented (especially myocardial infarction or renal insufficiency). Today, however, a diagnosis is usually made too late and only when acute symptoms and damage have already occurred. Treatment can then usually only alleviate symptoms, but in many cases no complete cure can be achieved.

The aim of the project is the development of a 'liquid-biopsy' based diagnostic test procedure, which for the first time will allow an individual assessment of the risk of arteriosclerosis and its organ-specific sequelae.

This project will be in cooperation with the hospital of the Ludwig-Maximilians-University (LMU) Munich, the Technical University of Munich (TUM) and the company TIB MOLBIOL and is funded by ZIM, Germany's largest innovation programme for small and medium-sized enterprises. 'ZIM' stands for 'Zentrales Innovationsprogramm Mittelstand', which means 'Central Innovation Programme for small and medium-sized enterprises (SMEs)'. It is a funding programme of the Federal Ministry for Economic Affairs and Energy (BMWi) that aims to foster the innovative capacity of SMEs.

Epigenetics Bio-Hackathon at ecSeq


Posted on December 11, 2018


btS Logo

Right now, seven Early Stage Researchers (ESRs) from the Marie Skłodowska-Curie Innovative Training Network EpiDiverse, majoring in biology, are trained by our ESR Adam in using the earlier developed WGBS and DMR calling pipelines. With three ESRs hosted by Prof. Dr. Peter F. Stadler at the bioinformatics chair of Leipzig university and four ESRs at ecSeq Bioinformatics, they are located in walking distance from each other. Thus, all of them have the unique possibility to get trained by experts from academia and industry. Two different views, two different working methods, one goal.

They already analyzed the first 24 bisulfite-treated DNA-Seq samples from pennycress (thlaspi). With 20GB per sample, our high-performances computer clusters ('epi' and 'diverse') were under heavy load. It took 20 hours to map the 24 samples to the thlaspi genome using the tool erne-bs5, while the other tool, segemehl, needed around one week. Calling differentially methylated regions (DMRs) with the tool metilene took ~4h.

Now the ESRs are trained by experts within the EpiDiverse network in how to interprete the results. By overlapping the DMRs with annotations, important meta information such as their genomic position (intron, exon, promoter) is added to the significant regions. Filters, clustering methods and elaborate visualizations will help the researchers to carve out relevant regions that are differentially methylated in stress situations and/or between different environmental conditions.

Research on Good Workshop Design


Research in biology has been progressively influenced by big data such as massive genome and transcriptome sequencing data. The handling and analysis of such data require computational skills that usually exceed the abilities of most traditionally trained biologists. In this interesting publication, ecSeq and others discuss the advantages, challenges and considerations for organizing and running bioinformatics training courses of 2–3 weeks in length to introduce biologists to the computational analysis of NGS data.

Open PhD Position


Posted on October 18, 2017




Inferring genomic information from bisulfite sequencing data



Background

DNA methylation variants can arise spontaneously, they can be under genetic control or they can be induced by the environment. In plants, some DNA methylation variants are stable across many generations whereas other variants are very transient. A good understanding of the transgenerational dynamics of DNA methylation variants is essential to understand their impact on heritable traits and their effect on adaptation. Current insight in the transgenerational dynamics of DNA methylation is limited to very few model plant species, but it is predicted that these dynamics are not constant among different plants. For instance, plant reproduction mode can have a large effect because asexual reproduction bypasses some of the epigenetic resetting mechanisms that normally occur during sexual reproduction. Adaptive differences in transgenerational stability may also differ between species with different life spans or from habitats of different environmental predictability.

Your PhD Project

In this project, we aim to investigate differences in DNA methylation dynamics between species with different life history traits. In close collaboration with other bioinformaticians and biologists, a best-practice pipeline for the analysis of plant bisulfite data will be developed, benchmarked, and provided to be applied to the Next-Generation Sequencing (NGS) data generated in the frame of different EpiDiverse projects. In addition, novel algorithms will be devised and implemented to better detect DNA methylation variants and search for important methylation haplotypes to better understand the epigenetic regulation. The special constellation of working at a bioinformatics company in very strong cooperation with the chair of bioinformatics at the university offers the unique possibility of gaining benefits from both: The clearly structured style of the work in a company will help implementing novel ideas from academia in the light of recent publications, resulting in a strong focus and high productivity.

Your Qualifications

We seek a bright, highly motivated, and enthusiastic bioinformatician, or computer scientist with significant interest in solving biologically motivated questions. Excellent programming skills with knowledge of at least one of the following programming languages are mandatory: Python, R, or C/C++/C#. A strong background in Next-Generation Sequencing (NGS) and/or (epi)genetics data analyses are an advantage. A high standard of spoken and written English is required, as are good quantitative and analytical capabilities, excellent interpersonal and communication skills, and the ability to work independently as well as part of a team.

Eligibility criteria

A university degree in a relevant field is required. Eligibility criteria of EU H2020 ITN programmes apply: candidates must be, at the time of recruitment by the host organisation, in the first four years (full-time equivalent) of their research careers and have not yet been awarded a doctoral degree. This is measured from the date when they obtained the degree which would formally entitle them to embark on a doctorate. Eligible candidates may be of any nationality but must not, at the time of recruitment, have resided or carried out their main activity (work, studies, etc) in the country of their host organisation for more than 12 months in the 3 last years immediately prior to the reference date.

How to apply

About EpiDiverse

EpiDiverse - Epigenetic Diversity in Ecology - is a Marie Skłodowska-Curie Innovative Training Network aimed at the study of epigenetic variation in wild plant species. This network joins academic groups from ecology, molecular (epi)genetics and bioinformatics with life science companies to explore epigenetic mechanisms and their adaptive relevance in natural plant populations.



The cross-disciplinary research program investigates how epigenetic mechanisms, in interaction with environments and transposable elements, contribute to variation that is relevant for the adaptive capacity of plants. By applying epigenomic research tools to a selection of different wild plants (including long-lived trees, annual and asexually reproducing species) we investigate how epigenetic mechanisms as well as their ecological relevance differs between plant species. Understanding the epigenetic contribution to adaptive capacity will help to predict species responses to global warming and can open new directions for sustainable agriculture and crop breeding.

The EpiDiverse consortium will train 15 Early Stage Researchers to become expert eco-epigeneticists, equipping them with the interdisciplinary skills - molecular, (epi)genomic, ecological and bioinformatics - to successfully tackle this new research area. EpiDiverse training will emphasize empirical and informatics skills to become fluent and creative in extracting knowledge from big ‘omics data in natural contexts.

EpiDiverse is funded by the EU Horizon 2020 programme and involves 12 partners from academia, non-profit organizations and industry located in the Netherlands, Germany, France, Spain, Czech Republic, Italy and Austria.

dandelion

Rubber from dandelions

In recent years the Russian dandelion Taraxacum koksaghyz, a previously neglected wild plant, has been investigated to be re-introduced as a valuable rubber crop that grows in moderate climates, like in Germany. The milky sap of the dandelion shows similarities to that of the rubber tree, and most importantly contains caoutchouc, the raw material for rubber production.

Together with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME, ESKUSA GmbH and hortilab, ecSeq GmbH will generate a high-resolution genetic map of Russian dandelion.


Christian Schulze Gronover

Dr. Christian Schulze Gronover (Fraunhofer IME) received the 2015 Joseph von Fraunhofer Prize for his work on the Russian dandelion and its application as a source of natural rubber. He is the coordinator of the project, which is funded by the German Federal Ministry of Education and Research (BMBF).


Fred Eickmeyer

Dr. Fred Eickmeyer (ESKUSA GmbH) specialized on breeding of dandelion. He wants to optimize and establish Russian dandelion to an alternative raw material for natural rubber.

Cooperation Agreement with Emmanuelle Charpentier's Laboratory


Posted on February 01, 2017


Today we signed a cooperation agreement with Prof. Dr. Emmanuelle Charpentier.

We are looking forward to this great partnership.


Prof. Dr. Emmanuelle Charpentiers

Prof. Dr. Emmanuelle Charpentier is best known for her role in deciphering the molecular mechanisms of the bacterial CRISPR-Cas9 immune system and repurposing it into a tool for genome editing. In particular she uncovered the mechanism beyond the maturation of non-coding RNA key for the CRISPR-Cas9 function. In collaboration with Jennifer Doudna's laboratory, Charpentier's laboratory showed that Cas9 could be used to make cuts in any DNA sequence desired. The method they developed involved the combination of Cas9 with easily created synthetic "guide RNA" molecules. Researchers worldwide have employed this method successfully to edit the DNA sequences of plants, animals, and laboratory cell lines.

Outstanding Research


The transcription factor MYC plays a key role in carcinogenesis. Together with scientists around Dr. Ingram Iaccarino (Christian Albrechts University) and Dr. Dr. Steve Hoffmann (University of Leipzig), Dr. Doose discovered a long non-coding RNA that is able to modulate MYC’s transcriptional network. This finding therefore has the potential to open new therapeutic opportunities for MYC associated cancers. The results were published in the renowned journal “Proceeding of the National Academy of Science of the United States of America” (PNAS).

Next-Generation Sequencing Data Analysis: A Practical Introduction, June/July 2016


Posted on July 06, 2016


Group Picture

Our workshop “Next-Generation Sequencing Data Analysis: A Practical Introduction” in Munich two weeks ago was a full success. Our two trainers gave the twenty participants from nine different countries an introduction on how to work with linux and how to analyze NGS data correctly. The gained knowledge will allow the researchers to start their own analyses and it will help them to discuss their bioinformatics problems or questions with bioinformaticians on an almost equal level.

For everyone who was not able to attend we will organize a second workshop in December 2016. It will be at the same location in Munich and it will cover the exact same topics. Perfect for beginners.


UPCOMING NGS DATA ANALYSIS WORKSHOP:

Next-Generation Sequencing Data Analysis: A Practical Introduction

  • Date: December 7 - 9, 2016
  • Location: Munich, Germany

Please find detailed information and a course program on the workshop's page.


Besides this introduction course we have planned three more workshops in fall 2016:


Lab journal with a portrait of ecSeq GmbH


Posted on May 04, 2016


Loborjounral cover

We recently received a visit by Tobias Hoffmann, a journalist from the German "Laborjournal" (German for lab journal). In its latest issue (from May 2nd, 2016) ecSeq GmbH and its founders, Dr. David Langenberger and Dr. Mario Fasold, are portrayed in a double-page article.

The article talks about our two founders, how they gained their doctorates from professor Stadler in Leipzig and their way to ecSeq GmbH. One of our business areas are workshops which train the participants how to analyze NGS data. We want to impart a discretionary competence as well as evaluation skills with the courses. Public workshops take place in Munich, Berlin, Prague or Oxford with about one third of the participants having an industrial (non-academic) background. This knowledge is important because nowadays every research application contains NGS analyzes.

Secondly, Hoffmann introduces our network of 45 highly skilled NGS experts to the readers. During project consulting ecSeq GmbH accompanies NGS projects which require complex bioinformatics solutions. Customers can book nearly everything: the analyses, the software or the complete planning of an experiment. All NGS experts are working in the background together with ecSeq GmbH.

Of course, the author asks the follow up question: 'Why should customers approach ecSeq and not the experts directly?' The answer is pretty simple: 'Because academic researchers with their reservations are often not very open-minded about inquiries from companies.' With ecSeq GmbH as intermediary, a trustful and well-managed collaboration is possible. This separation of industry and academia is very important for both, the companies and the researchers in our network.

We thank the "Laborjournal" for this great introduction of our company! You can get your free copy of the "Laborjournal" at universities and research facilities or on their website.


Let's Talk About Starting Your Own Company - ecSeq at Life Sciences Career Day Dresden


Posted on April 26, 2016


btS Logo

At the Life Sciences Career Day Dresden students from biology, biotechnology, biochemistry, medicine & pharmacy can get an impression about how their future could look like. We at ecSeq GmbH are very honored to represent the career path of a start-up company in the field of life sciences and to embold young scientists to realize their own ideas!

Deciding where to go after university is by far not trivial and has to be well thought out. Researchers have to realize that an academic career with the aim to get a professorship or the industrial path as an employee are not the only possibilities. We will explain and picture an interesting, but challenging middle course, the entrepreneurship. During our presentation we will tell the exciting story about starting our own company. We will describe how to turn the dream of a business into reality, talk about the initial period and finally, demonstrate how our daily work routine looks like. Afterwards, all upcoming questions will be answered.

The Life Science Career Day takes place on June 3rd, 2016 at the "Hörsaalzentrum" in Dresden, Germany.

It is organized by the biotechnology students initiative btS. We are looking forward to meet enthusiastic students who would like to discuss bioinformatics and its future with us.

These questions will be answered:

  • What is Next-Generation Sequencing?
  • What role does it already play in research and the daily clinical business?
  • Can a start-up in the field of NGS bioinformatics be successful?

RNA Expert - Dr. Martin Smith


Posted on March 21, 2016


Dr. Martin Smith

We are very pleased to introduce Dr. Martin Smith as a member of our NGS Expert Network.

Dr. Martin Smith is a computational biologist with a strong background in biology. As a child he grew up in Canada and he always dreamt of becoming a biologist. He majored as an undergraduate in microbiology and immunology at the University of Montreal, but he quickly realised this wasn’t his field. Switching to the emerging field of bioinformatics was an enthusiastic yet challenging decision for him, as it required rewiring his brain around abstract informatics concepts and discrete mathematics.

To this day, he is very passionate about bioinformatics and would recommend a cross-disciplinary career path to anyone. He has worked in 5 different cities across 3 different continents, namely Montreal (University of Montreal); Quebec City (Infectious Disease Research Centre—CHUL); Brisbane (Institute for Molecular Bioscience); Leipzig (Interdisciplinary Center for Bioinformatics); and Sydney (Garvan). He received his doctorate in Genomics and Computational Biology from the University of Queensland in 2012. His doctor's thesis was supervised by Prof. Dr. John Mattick and Prof. Dr. Peter F. Stadler.

His research revolves around characterising the “regulome”, i.e. the biological mechanisms that control how genes are activated and repressed. He is particularly interested in how non-protein coding regions of the genome can regulate gene expression at the level of RNA.

De Novo Transcriptome Analysis - Assembly and Differential Gene Expression


Outstanding Research

In 2014 Dr. Alexander Donath co-authored the Science paper Phylogenomics resolves the timing and pattern of insect evolution, which was honoured as a research highlight by Nature Reviews Genetics.

'... In this research, novel approaches were used to produce a robust phylogenomic tree of insects, which will now serve as a reference point for future research.' (Nature)

Science Magazine      '... The study authors, who are part of an international consortium working on the 1K Insect Transcriptome Evolution (1KITE) project, began their work in 2011 in hopes of using newly available sequencing technology to clarify insect relationships previously only investigated using morphological evidence or smaller molecular datasets. They sequenced transcriptomes from 103 insect species distributed across all living insect orders. They also drew data from previously published whole-genome sequences of 14 arthropod species, as well as from transcriptomes of 27 additional species. They then narrowed down their genetic data to 1,478 protein-coding genes that are present in all of the species analyzed. ...'

Introducing Knowledge-Driven NGS Solutions


Posted on September 16, 2015


Knowledge-Driven NGS Solutions

Nobody can be an expert in everything. However, biomedical projects increasingly demand expert knowledge in more than a single field. In fact, up-to-date expert knowledge is key to generating impactful biological insights.

To this end, we established an extensive network of outstanding scientists, covering various research fields relevant to NGS. The idea is that, together with the customer, we assemble a panel of experts that is able to develop an optimal strategy for the specific challenges of the project (see our white paper).

Our bioinformatics team can then rapidly implement a software solutions since we already have a library of analysis modules for many NGS applications.

As usual, these hands-on workshops have a strong focus on practical experience meaning that you analyze typical NGS datasets. Our trainers will directly interact with you and give valuable feedback.

Our workshop series 2014 will consist of four separate courses:

For beginners, we have the RNA-seq Bioinformatics: A Practical Introduction course which will cover all the basics required for NGS analysis like file formats, quality control, read processing and read alignment, all based on an example RNA-seq dataset.

We are very happy that we could convince Dr. Michael Hackenberg, the developer of one of the most-used microRNA gene prediction tools for small RNA-seq data (miRanalyzer) to join us for our microRNA workshop. This course titled microRNA Analysis Using High-Throughput Sequencing will cover the essential steps of small RNA-seq analysis from microRNA prediction to extensive downstream analyses.

We also have a workshop on DNA Methylation Analysi where Helene Kretzschmer will show you how she took care of her data in the MMML-Seq study of the International Cancer Genome Consortium (ICGC).

Lastly, there is the workshop Discovering standard and non-standard RNA transcripts where Gero Doose will train you on advanced methods of transcriptome analysis. Gero has a strong background in transcriptome analysis, finding different isoforms, fusion-transcripts or circularized RNAs.

There is an early-bird discount which applies until end of april.
