Next-generation sequencing (NGS) offers the scalability, speed, and resolution to evaluate targeted genes of interest. Targeted panels with focused content helps targeting desired set of genes only thereby reducing cost of testing. MedGenome labs has been performing exome testing and targeted panel testing by NGS over the last 8 years and have so far tested more than 100,000 samples. The challenge we face in the cost sensitive Indian market is in giving low cost tests that can be used by even the lower income group. We take pride in being the first to introduce the clinical exome panel (targeting only the clinically relevant genes) to the Indian market thereby ensuring the patients get a cost-effective, at the same time, clinically productive NGS test. We have been using the TWIST comprehensive exome the last two years the content of which has been well evaluated by us. It’s content is comparable and at times better than most of the currently available exomes in the market. Our diagnostic yield with the exomes has been comparable to the other exomes we were using till then and also comparable to the published data. We are also using 10 different TWIST targeted panels which gives us a cost-effective alternative to exomes. TWIST targeted somatic panels work well with the very bad quality FFPE too, with lesser failures due to bad quality data. Our experience with the team for panel designing and troubleshooting also have been excellent. To conclude, our experience with TWIST exomes and targeted panels have been very good and it offers us a good cost-effective option needed for the cost-sensitive Indian market.

In this poster, we demonstrate Twist's target enrichment systems as a sensitive and informative approach combining library preparation and 30 minute Fast Hybridization for detecting viral agents that can be RNA or DNA as well as single- or double-stranded. The data show that our SARS-CoV-2 Research Panel can detect the virus with as few as 10 copies of SARS-CoV-2 genome. Extending our results beyond single infections, the data demonstrate that Twist’s Respiratory Virus Research Panel simultaneously detects multiple viral agents which can then be sequenced with excellent coverage in a model of co-infection.
