Using VarSeq to Improve Variant Analysis Research Workflows


Many questions must be answered when analyzing DNA sequence variants: How do I determine which variants are potentially deleterious? Is the sequencing quality sufficient? How do I prioritize the results? Which annotation sources may help answer my research question?

In this webinar presentation, we will review workflow strategies for quality control and analysis of DNA sequence variants using the VarSeq software package from Golden Helix. VarSeq is a powerful platform for analysis of DNA sequence variants in clinical and translational research settings. VarSeq provides researchers with easy access to curated public databases of variant annotation information, and also enables users to incorporate their own local databases or downloaded information about variants and genomic regions.

The presentation will include interactive demonstrations using VarSeq to analyze variants found by exome sequencing of an extended family with a complex disease. We will review strategies for assessing variant quality, applying genomic annotations, incorporating custom annotation sources, and creating variant filters in VarSeq. We will also demonstrate the PhoRank gene ranking algorithm and its application for prioritizing variants.
