GnomAD v4 Released: Enhanced Data and Golden Helix Curation for VarSeq Users

         February 7, 2024

The Broad Institute’s release of gnomAD v4 needs no introduction as the data in this release is highly sought after by professionals in the genetics community, and the v4 release has a lot to boast about! The v4 release is roughly five times larger than the v2 and v3 releases combined and includes data from 807,162 total individuals. Naturally, exome… Read more »

Using Liftover to Curate GnomAD v4 for GRCh37

         January 25, 2024

We are excited to announce the release of our gnomAD v4 annotation tracks for VarSeq. This version of the GnomAD database represents a significant leap forward, including data from an impressive cohort of over 800,000 individuals — a remarkable 5x expansion compared to the previous releases. Notably, this dataset is comprised of two distinct callsets: exome sequencing data from 730,947… Read more »

Coming to SVS: LiftOver Capability

         July 23, 2020

The world has been making a shift to use GRCh38 human genome reference coordinates, but the transition has not been fast. Many of the mainstay human catalog projects are changing to use native GRCh38 catalogs, or are remapping their current data to GRCh38 coordinates. While this seems to be the advancing goal, it is leaving researchers and analysts with the… Read more »

CADD Scores: New and Improved v1.4 and v1.5

         June 18, 2020

The University of Washington’s Combined Annotation Dependent Depletion (CADD) algorithm measures the deleteriousness of genetic variants. This includes single nucleotide polymorphisms (SNVs) and short insertions and deletions (indels) throughout the human reference genome assembly. This algorithm was introduced in 2014 and has since become one of the most widely used tools to assess human genetic variation. Since 2014, the algorithm has been… Read more »

Updated GRCh38 VarSeq Project Templates

         February 4, 2020

As many of our users know, VarSeq comes shipped with various project templates that are designed to give users a baseline workflow to get started with their projects. These templates are tailored for various applications including tumor-normal, trios, cancer and hereditary gene panels, and ACMG Guidelines workflows. The templates contain application-specific annotation sources and algorithms that will automatically load into… Read more »

Updated Annotations: The new and improved gnomAD 2.1.1

         September 19, 2019

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 »

Using GRCh38 for Clinical Interpretation: Now Possible with Our Custom LiftOver Tracks

         January 23, 2018

There are many good reasons why the pursuit of the highest quality genomic interpretation would lead you to the latest human reference. It is more complete and fixes incorrect or partially missing genes that have known implications for human disease. While most major projects cataloging human populations have plans to re-do all their genomic alignments to the new human reference… Read more »

6 Population Catalogs Compared with the ExAC 61,486 Exomes

         November 13, 2014

To say the announcement of Dan MacArthur’s group’s release of the Exome Aggregation Consortium (ExAC) data was highly anticipated at ASHG 2014 would be an understatement. Basically, there were two types of talks at ASHG. Those that proceeded the official ExAC release talk and referred to it, and those that followed the talk and referred to it. Why is this… Read more »
