Warehouse Workflow Spotlight: Part 3

Apr 14, 2026

Many labs already use DRAGEN upstream, but want more control over what happens after variant calling is complete. VSWarehouse 3 connects those outputs to downstream tertiary workflows that labs can automate, configure, and adapt to their own interpretation and reporting process. Using DRAGEN with VSWarehouse 3: A Better Path to…

Streamlining Carrier Analysis with VSClinical

Nov 13, 2025

Carrier screening is an important component of reproductive genetic testing, helping identify individuals or couples at increased risk of passing on inherited conditions to their children. When both partners carry a pathogenic or likely pathogenic variant in the same gene associated with an autosomal recessive condition, or when a pathogenic…

Integrating Genomenon Mastermind Curated Variants in VarSeq and VSClinical

Sep 23, 2025

When performing variant classification using VarSeq’s ACMG classifier, a large number of variants inevitably fall into the category of variants of uncertain significance (VUS). This is because much of the evidence required for confident classification cannot be programmatically evaluated. Take PS3, for example, the criterion for functional evidence. This criterion…

Importing External PGx Calls for Extended Gene-Drug Reporting in VarSeq

May 27, 2025

Pharmacogenomic (PGx) analysis empowers researchers and clinicians to tailor drug therapies based on a patient’s genetic profile, but not all regions of the genome are easy to interpret. Genes like CYP2D6 and HLA-A are tricky when it comes to rendering diplotype calls. This is due to a number of factors…

Collapse Phased Variants in VarSeq

Sep 12, 2024

In a recent blog post, we explored how phased genotypes provide crucial insights by separating variants into distinct haplotypes—groups of alleles inherited together from a single parent. We also discussed how the combined impact of multiple variants within the same gene can significantly differ from their individual effects. However, accurately…
