InView™ 2-weeks Exome is the solution for your cutting-edge clinical research. Convince yourself and benefit as many other researchers already.
The exome accounts for ~1% of the human genome and consists of functionally relevant coding regions (exons) which are most likely to cause differences in phenotypes. Exome enrichment is a powerful tool for discovering relevant variations by sequencing only a fraction of the human genome.
Exome analyses allow a closer insight in these target regions providing valuable information for:

1. Where do I get my results and what do they look like?
All raw data as well as the analysed data can be downloaded via your secured myGATC account. Example analysed data of 30x coverage are available for download after login.
2. What coverage should I use?
For SNP calling in heterozygote organisms we recommend at least 30x coverage. A higher coverage will increase the confidence of SNP calling. To confidently discover variants in inhomogeneous samples like e.g., DNA extracted from normal and tumor cells, a higher overall coverage should be chosen. The amount of data needed to reach a certain coverage on the DNA of interest depends on the ratio normal/tumor DNA. Please note, that due to varying efficiency of the enrichment baits, the targeted regions are not covered evenly (see below).
3. How do you handle PCR duplicates?
PCR duplicate rates are directly correlated to the quality and amount of starting material provided. Library preparation with less than the recommended amount of DNA requires additional PCR cycles to generate enough material to load the sequencer. Hence, the PCR duplicate rate is dependent on the sample and cannot be influenced by GATC Biotech. The duplicates are not excluded from the calculation of the average on-target coverage. Based on our experience with the sequencing of human samples we typically receive PCR duplicate rates of approx. 5% for high-quality DNA.
If further bioinformatics are ordered (e.g. SNP identification) only one copy of the duplicate read pair is kept in the alignment. The rest are excluded from further analysis to prevent any bias.
4. Which and how much starting material should I send?
Raw data output guarantees currently only apply for freshly isolated, unamplified and pure human DNA samples (minimum 3 µg). Contamination by DNA of other species (> 3%; especially from closely related ones) might interfere with the enrichment of the human DNA and also reduces the total amount of human DNA in the provided sample. Whole genome amplified (WGA) DNA or DNA from archived tissue like e.g., Formalin-Fixed Paraffin Embedded (FFPE) samples is usually accepted. Please contact us if you need any details.
5. What do you mean by overlapping reads?
The fragmentation of genomic DNA according to the Agilent SureSelectXT protocol and following downstream processing produces a Gaussian distribution of DNA fragments with different lengths. A small percentage of the resulting library fragments have an insert size below 200bp. Sequencing of those library fragments with 100bp paired end reads will generate partially overlapping reads which cover the same bases and hence create an artificial doubling of coverage at those positions. To assure accurate analyses those bases are excluded from the calculation of the average on target coverage and further downstream analyses. Furthermore GATC is continuously optimising its protocols to minimise the number of overlapping bases.
6. What is the quality of the data?
When sequencing human samples in 100bp paired-end mode GATC Biotech typically achieves over 80% of base calls with a quality value higher than Q30 ( >99.9% accurate).
7. Do you guarantee a certain on target output?
For samples which have successfully passed initial quality check at GATC Biotech, we will guarantee the on target output ordered by you. Average on target coverage is calculated as the sum of the mapped bases (without overlapping bases) at each target position, divided by the number of bases in the target (bases on-target / size of target region).
8. Which genes are enriched?
The target region corresponds to the bait coordinates of the Agilent SureSelectXT Human All Exon V5 Kit (approx. 50 Mb, comprising 21.522 genes and 357.999 exons). Target region (bed file) of Exon V5 Kit are available here.
9. Are all genes covered with 30x?
Due to varying efficiency of the enrichment baits (e.g., GC / AT content) targeted regions are covered differently and the range and uniformity of coverage varies over the target region. GATC Biotech applies the most recent Agilent Human All Exon kit design (V5) with improved design algorithms to better capture difficult regions and increase coverage uniformity.
10. How much starting should I provide?
For optimal results we require at least 3 µg double-stranded, purified, high molecular and RNA-free DNA (concentration approx. 200 ng/µl; OD 260/280 ≥ 1.8; OD 260/230 ≥ 1.9).
11. What kind of quality controls do you perform?
The quality and quantity of each incoming sample will be determined by appropriate methods (e.g. agarose gel analysis / Qubit® Fluorometer / NanoDrop / Agilent 2100 Bioanalyzer). Further quality controls are performed at various steps of the process.
