Two Siblings, Two Diagnoses: Independent De Novo Findings in a Multi-Affected Family

Jun 30, 2026

Family-based analysis is one of the most powerful tools in rare disease genomics. When multiple relatives are affected, investigators naturally look for a shared genetic explanation, often with good reason. Shared inheritance patterns frequently provide the critical clue needed to identify a causal variant. The case described here is a…

Cryptic Splice Site Detection: How CI-SpliceAI and Whole Genome Sequencing Uncover What Exome Panels Miss

Jun 4, 2026

Aberrant splicing is one of the most consequential and least visible mechanisms driving human genetic disease. While variants disrupting the canonical GT/AG dinucleotides at exon–intron boundaries can be easily detected, some variants silently reshape splicing from deep within introns, far from the regions that targeted panels and whole exome sequencing…

Follow the Fusion: How Gene Fusions Shape Brain Cancer and How VarSeq Finds Them

May 26, 2026

Brain cancer remains one of the most difficult malignancies to treat, which is largely explained by basic biology. The blood-brain barrier (BBB) blocks most systemic therapies from reaching tumor cells, and the molecular heterogeneity of brain tumors makes it hard to find treatment strategies that work broadly. However gene fusions…

Long-Read Part 2: Methylation Analysis

May 12, 2026

DNA methylation plays a critical role in gene regulation and is increasingly recognized as a clinically meaningful biomarker in oncology. With the rise of long-read sequencing, we now have the ability to detect base modifications alongside small variants and structural variations. In this post, we’ll walk through how VSWarehouse and…

Genotype: Unusual GT Fields in Cohort and Trio Analysis

May 7, 2026

If you spend enough time staring at VCF files, you eventually start to feel like you’re reading a secret language. Most of the time, things are straightforward with the Genotype (GT) representation: 0/0, 0/1, 1/1. Easy enough. But then one day, you import your VCFs for a trio analysis and…

Brain Tumor Awareness Month

May 5, 2026

This May, we’re recognizing #GrayMay, a month dedicated to raising awareness about brain tumors. In this blog post, I want to share something practical regarding precision medicine of gliomas: for gliomas, the diagnosis is no longer based on histology alone. Molecular profiling now helps define the tumor entity, clarify prognosis,…

Long-Read Part 1: Structural Variant Analysis

Apr 28, 2026

End-to-End Structural Variant Analysis for Long-Read Data with VarSeq and VSWarehouse Long-Read Data Long-read sequencing technologies like PacBio HiFi have transformed our ability to detect structural variants (SVs) with greater accuracy and resolution than ever before. Unlike short-read sequencing, which often struggles to span the repetitive or complex genomic regions…

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…
