Copy Number Variants Using AMP Guidelines

Oct 10, 2019

The common approaches to detecting copy number variants (CNVs) are chromosomal microarray and MLPA. However, both options increase analysis time, per sample costs, and are limited to the size of CNV events that can be detected. VarSeq’s CNV caller, on the other hand, allows users to detect CNVs from the…

Variant Interpretation with VSClinical: RET-KIF5b Gene Fusion

Sep 24, 2019

Gene Fusion Background Gene fusions are hybrid genes that result from translocations, interstitial deletions, or chromosomal inversions that can lead to constitutive gene activation and result in increased or abnormal protein production. Increased or abnormal protein production subsequently can play an important role in tumorigenesis and thus identifying and evaluating…

Automating & Standardizing Your NGS Workflow: Part IV

Sep 10, 2019

We have covered a lot of ground in this Automating & Standardizing Your Workflows blog series. First, we saw how to perform secondary analysis with Sentieon to generate the necessary VCF and BAM files for tertiary analysis in Part I. The implementation of VSPipeline allowed for rapid import and project…

Shared Data in VarSeq

Jul 22, 2019

When using VarSeq; annotations, application settings, and assessment catalogs are all stored locally. Sometimes these resources can grow to large space grabbing directories, causing you to either purchase additional storage devices or getting rid of previously downloaded resources you might need down the road. But there’s hope! You can set…
