Accurate Annotations: Updates to the NHLBI Exome Sequencing Project Variant Catalog

         May 19, 2015

Since its early release in early 2012, the population frequencies from the GO Exome Sequencing Project (ESP) – from the National Heart, Lung and Blood Institute (NHLBI) have been a staple of the genomic community. With the recent release of ExAC exome variant frequencies, the ESP has been surpassed as the largest cohort of publicly available variant frequencies (by nearly… Read more »

Supercentenarian Variant Annotation: Complex to Primitive

         March 19, 2015

In a previous blog post, I demonstrated using VarSeq to directly analyze the whole genomes of 17 supercentenarians. Since then, I have been working with the variant set from these long-lived genomes to prepare a public data track useful for annotation and filtering. Well, we just published the track last week, and I’m excited to share some of the details… Read more »

The State of Variant Annotation: A Comparison of AnnoVar, snpEff and VEP

         June 25, 2014

Up until a few weeks ago, I thought variant classification was basically a solved problem. I mean, how hard can it be? We look at variants all the time and say things like, “Well that one is probably not too detrimental since it’s a 3 base insertion, but this frameshift is worth looking into.” What we fail to recognize is… Read more »

Demystifying the Representation of Structural Variants Imported into VarSeq

         May 20, 2024

VarSeq enables users to import structural variants for annotation, filtration, and subsequent clinical or other analyses. Structural variants are often called during secondary analysis as belonging to two broad categories – Copy Number Variants (CNVs) with the file suffix “…_CNV.vcf” and Breakends with the file suffix “…_SV.vcf”. This blog will give some insight into how structural variants are triaged when… Read more »
