Lock in Annotation Source Versions to Increase Workflow Consistency

         February 25, 2021
Annoation Sources

Next-generation sequencing generates an immense amount of data which is then subject to a multi-step process to establish a validated bioinformatic pipeline. From processing raw sequence data to the detection of genetic mutations, establishing a validated and consistent bioinformatic pipeline makes a huge difference in the quality of patient care and accuracy of results. In this blog, we are focusing… Read more »

GnomAd screenshot

VarSeq recently received major upgrades in a wide range of areas, one of these areas includes adding annotations such as GnomAD. This includes new fundamental methods of CNV ACMG guideline processing but also a large number of small additions in annotations. One addition is the application of gnomADs – Gene Constraints. This provides various metrics for pathogenicity on a per… Read more »

What You Need to Know About Staging Annotations

         January 22, 2021

Annotating genomic variants is a very complex process but perhaps the most important part of next-generation sequencing variant analysis. Here at Golden Helix, we recognize the importance and value of having the most up-to-date sources available and curating new annotation sources as they become available for variant analysis. Golden Helix has curated over 100 annotation sources for human variant analysis… Read more »

Updated Annotations: RefSeq with MANE Select Transcripts

         December 17, 2020

Our upcoming release of VarSeq is one of the largest we’ve ever had with our software! It comes with an extensive list of polishes and new features like our recently mentioned ACMG CNV classifier and a redesigned reporting interface with updated templates. Additionally, this new release is also paired with some major upgrades to our list of new and supported… Read more »

Updated Annotation: BRCA Exchange

         October 30, 2020

Our team is regularly updating and curating annotations, most recently the BRCA Exchange. Breast cancer is known to occur in approximately 10% of the female population and if there is a damaging mutation in the breast cancer gene (BRCA), that rate increases to 65%. Although genetic testing can identify mutations in BRCA, a tumor suppressor gene, it has been difficult… Read more »

Fast Annotations Around the Globe: Our Sydney and Frankfurt Data Mirrors

Customer Publications

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 »

Updating Somatic Annotation Catalogs: ICGC and COSMIC

         October 28, 2019

Golden Helix works to keep incorporating and updating great somatic annotation catalogs for our VSClinical users. We currently have the updated version of one of the largest cancer databases from the International Cancer Genome Consortium, or ICGC. Version 28 has been improved by integrating ClinVar and CIViC clinical annotations, and as always, increasing the number of mutations listed. The current… 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 »

VarSeq Variant Annotation Normalization

         July 18, 2019

Smoothing Hurdles into Speed Bumps when creating Annotation Sources Although most researchers assume that getting the pile of VCF sequence files is the largest hurdle in moving towards an analysis, there still exists the looming step of normalizing the variant calls in annotation sources to make variant comparison easier. In this ever-refining field of study, VarSeq continually works to increase… Read more »

VSClinical Updates & a Tour of Cancer Annotations – Webcast Q&A

         November 8, 2018

This webcast generated a lot of great questions about the content covered in the video above. I have summarized our Q&A session below and included some questions I didn’t have time to answer during the live event. If you have any further questions, reach out to us at info@goldenhelix.com!

New & Improved ClinVar Annotations

         March 13, 2018
ClinVar

ClinVar is the NCBI variant database that focuses on the categorizing of variant alleles and their interpretation from a clinical standpoint. This has made it a great resource, especially for those seeking variant allele disease correlations and pathogenicity. And this all worked fairly well, but it was changed… Previously, the ClinVar variant track annotation took some time to curate due… Read more »
