CADD Scores: Rank and Filter in Harmony!

         May 19, 2016
VSClinical algorithm

There used to be much energy expended at conferences, bioinformatics forums and even publications about what was the better strategy for interpreting variants of clinical significance: Rule-based filtering and classification mechanisms or rank-based prioritization through all-encompassing “pathogenicity” scores. Both have shown to be effective. Rule-based systems, as exemplified in this filtering diagram in Baylor’s ground-breaking paper on clinical whole-exome sequencing… Read more »

N-of-One Integration comes to VSReports

         April 28, 2016

Submit directly to N-of-One from VarSeq If you or your lab uses N-of-One solutions for clinical annotations, here’s some good news: You can now submit directly to N-of-One from VarSeq! N-of-One’s set of preferred transcripts may differ from those outputted by our algorithms in VarSeq, so our solution was built with that in mind. Our slick, easy to use, and… Read more »

Practical VarSeq Example – Cancer Gene Panel

         March 15, 2016

Recently, we were excited to find a new example data set for cancer gene panels. We have included this example data in the latest e-book by Dr. Andreas Scherer, Genetic Testing for Cancer as well as in the latest cancer webcast . This data is from Illumina’s MiniSeq sequencer and the TruSight Cancer panel. The BAM and VCF files for three samples… Read more »

Although we had a great set of questions at the end of our presentation, we didn’t have time to answer all of them, so here is a selection of… Read more »

Match Gene List algorithm not just for genes

         December 17, 2015

The most common use of the VarSeq Match Gene List algorithm of course is to determine if the variants in your data set are contained within your genes of interest. As an example of this, say you are working with a whole exome trio and only want to consider those variants that are contained within the 56 genes recommended by… Read more »

Handling Singletons & Complex Pedigrees with Gene Count Algorithms

         December 3, 2015

As VarSeq’s adoption has grown among analysts using whole exome data to diagnose rare diseases, a couple of family designs outside of the common trio of an affected child and both parents have come up frequently. While having both parents provides the maximum power to discover de novo mutations and recessively inherited variants, it is not always possible to contact… Read more »

Tumor-normal demo project comes to VarSeq

         December 1, 2015
VarSeq

With the release of VarSeq 1.3.1 we have included a new demo project to showcase a single tumor-normal pair analysis workflow. The project can be accessed through VarSeq and VarSeq Viewer by going to File > Open Example Projects > Example Tumor-Normal Pair Analysis. This project contains an exome pair (Normal-N990005 and Tumor-T990005) from the Gastric Cancer study Exome sequencing of… Read more »

A New and Unexpectedly Powerful VarSeq Feature

         November 17, 2015

With the release of VSReports, we added the ability to “select” rows of your filtered output (often variants, but potentially things like coverage regions or genes) with a new feature dubbed “Record Sets”, but more often described as “colored checkboxes” for your tables. Although necessary for the important task of marking primary, secondary or other sets of variants for a… Read more »

New VarSeq Demo Projects

         November 12, 2015

As VarSeq gains in popularity, we want to give Viewers and customers alike the opportunity to look at projects that are completed from start to finish. To this end, VarSeq (and VarSeq Viewer!) currently comes with two demonstration projects, Example TruSight Cardio Gene Panel and Example YRI Exome Trio Analysis. To access these projects from the VarSeq start page go to… Read more »

Analyzing a Single Sample Exome in VarSeq

         October 22, 2015
Exome

While VarSeq comes with a number of starter workflows that are stored as templates, customers also have the option of creating filter chains from scratch; analyzing a single exome may require you to do exactly that. In this blog, I’ll go through analyzing a single exome and generating a list of variants for further study. After importing the variant data… Read more »

What’s in a Name: The Intricacies of Identifying Variants

         May 26, 2015

There’s a strong desire in the genetics community for a set of canonical transcripts. It’s a completely understandable and reasonable thing to want since it would simplify many aspects of analysis and especially the downstream communicating and reporting of variants. Unfortunately, biology isn’t so tidy as to provide a clear answer for which transcript is the important one. Consequently, there… Read more »
