Variant Interpretation with VSClinical: RET-KIF5b Gene Fusion

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 this type of biomarker is important in the cancer workspace….

Updated Annotations: The new and improved gnomAD 2.1.1

The Broad Institute team led by Dan MacArthur announced the release of gnomAD version 2.1 at last year’s ASHG conference. This new version boasted data from 125,748 exomes and 15,708 genomes, but the greater updates were the improved QC refinement and more discrete sub-population break downs. Although the majority of samples were counted in the previous 2.0.2 release, the additional… Read more »

Optimizing your CNV Analysis in VSWarehouse

VSWarehouse Updates

We recently hosted a webcast covering the value and application of VSWarehouse through VarSeq. Not only is VSWarehouse a solution for storing your NGS data in a central repository, but it also provides a means to enhance the tertiary analysis done in VarSeq. VSWarehouse will store all your sample/variant data but also stores your catalogs of pathogenic variants, clinical reports, and has the capability of filtering/querying on all your stored data quickly. In addition,… Read more »

Using the GRCh38 reference assembly for clinical interpretation in VSClinical: Webcast Q&A

Upcoming Webcast on CNV Calling of Target Regions

CNV calling

Copy Number Variations (CNVs) play an important role in human health and disease, and the detection of CNVs in clinical samples has the potential to improve clinical diagnoses and inform treatment decisions. Yet until now, if you wanted to have CNVs on your targeted gene samples, you would need an alternative assay such as Chromosomal Microarrays (CMAs). In this webcast,… Read more »

Let There Be Genomes: Big Data Genomics Webcast Teaser

Big Data Genomics

Big data is here, but fear not, you don’t need a Hadoop cluster to analyze your genomes or your cohorts of tens of thousands of samples! It turns out, for the kind of algorithms employed in variant annotation and filtering, running optimized local programs is often faster anyway. As we support our diverse customer base, we have definitely seen the… Read more »
