In the 1990s the genetic industry voiced a request for a variant catalog that incorporates associated variant information such as phenotypic and metabolic pathways. The call was answered by NCBI, which created dbSNP; dbSNP became publicly available in 1998 and around 1.5 million variants. Fast forward to the present and dbSNP now contains over 2 billion SNPs spanning human, rat,… Read more »
The potential of genetic testing to impact a patient’s life has been greatly accelerated by the sharing of variant interpretations done by clinical labs in public repositories such as ClinVar. This is not an inevitable outcome, but the persistent work and advocacy of people like Dr. Heidi Rehm and organizations like ClinGen. We recently participated in a survey and vetting… Read more »
In the search for disease causing mutations it is important to determine if the variant has been previously observed in humans and at what frequency. With the advent of increasing genomic information, there is now a variety of different databases and annotation sources that can be utilized. For some, this could be a tedious task that leads only to implementing… Read more »
If you have watched this blog over time, it would be no surprise that Golden Helix invests a lot in curating genomic annotations for use with our clinical and research analysis products. Often, we spend considerable time on the attention to detail necessary to ensure the best experience for any data source by cleaning, normalizing, documenting and then distributing it through our data annotation server. Many annotations… Read more »
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 »
Golden Helix is excited to announce a new round of novel and updated annotations; including a frequency track, a region track, and a gene track. All three of these tracks were created with the use of VarSeq and its Convert Wizard functionality. First, the expansive 1000 genomes track (1kG) has been updated to include sub-population allele frequencies and heterozygous and… Read more »
This month we hosted two, incredible webcasts officially announcing the latest CNV annotation capabilities our Software Engineering Team has been hard at work on for the past couple of months. Our first webcast, Comprehensive Clinical Workflows for Copy Number Variants in VarSeq, was presented by Golden Helix’s VP of Product & Engineering, Gabe Rudy, who reviewed the expanded capabilities of… Read more »
Gabe Rudy gave a fantastic presentation yesterday on the latest additions to VS-CNV annotations. If you weren’t able to join us for the live event, you can access the recording and webcast slides here: Comprehensive Clinical Workflows for Copy Number Variants in VarSeq. Additionally, there were many great questions asked that we wanted to share with the community. Question: Can I… Read more »
