Webcast Recap In the recent webcast “Exploring New Features and Clinical Reports in the ACMG Guideline Workflow”, Gabe and I took viewers through an evaluation with CNVs and SNVs according to the ACMG Guidelines where we generated and customized a clinical report. Along the way, we highlighted many new features that will soon be available in the upcoming VarSeq release…. Read more »

Loss-of-Function Splice Variant in MTHFR

         November 26, 2020

In this blog post, I will be analyzing a loss-of-function splice variant in MTHFR using VarSeq. In the search for clinically relevant variants contributing to rare disorders, efficient filtering strategies are an important step in eliminating disinteresting variants. However, any applied filters must also ensure no interesting variants inadvertently get filtered out. Golden Helix provides the tools to complete this… Read more »

Webcast Follow-up: Evaluating CNVs with VSClinical’s New ACMG Guidelines

         November 19, 2020

In our previous webcast, Evaluating CNVs with VSClinical’s New ACMG Guidelines, we focused on a CNV deletion (12:27715515-29628122×1) in which the patient had a known disorder called Brachydactyly type E. The CNV was isolated using our VS-CNV caller and applied to the ACMG CNV guidelines using the intuitive steps of VSClinical. If you missed the webcast, you can watch the… Read more »

Webcast Recap: Evaluation of CNVs with VSClinical’s New ACMG Guideline Workflow

         November 10, 2020

In the webcast, Evaluation of Copy Number Variants with VSClinical’s New ACMG Guideline Workflow, we discussed how VSClinical implements Section 4 of the ACMG guidelines. Specifically, we focused on integrating literature and publications to assess the pathogenicity of a CNV event when there was a lack of dosage sensitivity information. One of the primary pieces of evidence for evaluating genes… Read more »

In lieu of conferences making the absolutely necessary decision to cancel this year’s conference, we created our Virtual 2020 Conference Booth! Even though it will never compare to the real deal, we hope you enjoy this blog post containing a few events we had planned this year. To start, let us paint the picture with some of our favorite conference… Read more »

Golden Helix’s NGS-Solutions for Clinical Variant Analysis: VSWarehouse

         August 27, 2020
VSWarehouse Updates

We have now reached the final blog of the NGS-Solutions for Clinical Variant Analysis series. Part I of this series explored the capture of variant classifications in the VSClinical environment when following the ACMG and AMP guidelines. Part II was similar in content but for the capture of clinically relevant copy number variants as well as using a CNV catalog… Read more »

Golden Helix gets full marks in ClinGen’s list of Genomic Analysis Software Platforms

         August 26, 2020
Clinical Genome Resource

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 »

WT1 Mutations: Side-by-Side Germline and Somatic Variant Evaluation in VSClinical

         July 28, 2020

It is common knowledge that variants can be germline or somatic depending on whether the variant was inherited or acquired after birth. A well-known example is cancer-causing mutations in the BRCA genes, wherein the mutation may or may not have been inherited. Understanding the origin of the cancer-causing mutation is important when assessing potential treatment options as well as identifying… Read more »

Featured in The Journal of Precision Medicine: Diagnosing and Tracking COVID-19 Infections Leveraging Next-Gen Sequencing

         July 8, 2020

It is an honor to be published in The Journal of Precision Medicine’s June/July 2020 issue in an article co-authored by Dr. Christiane Scherer and myself, “Diagnosing and Tracking COVID-19 Infections Leveraging Next-Gen Sequencing.” In this article, I detail: The key facts about COVID-19, reviewing the epidemiology, reservoir hosts, transmission routes, and clinical manifestation. Answering the question of how Next-Generation Sequencing can… Read more »

Coping Mechanisms in the COVID-19 World

         June 4, 2020
Working from home

Like many of you, I was supposed to attend the 2020 ACMG Meeting in San Antonio this March with a few colleagues. In addition to attending the conference, my first blog post for Golden Helix was going to be about our time at the conference. Thanks to the world-wide COVID-19 pandemic, none of us got to attend the conference. (We… Read more »

Genome Wide Association Tests and Mixed Linear Models in SVS

         May 19, 2020
SVS 8

SVS offers several options to conduct genome wide association tests and mixed linear models. At times, it can be challenging to decide which test, model, or adjustments to use when setting up your analysis. I want to briefly explore the options available in SVS for association tests, and mixed linear models to hopefully facilitate in understanding and choosing which options… Read more »

Powerful Cohort Analysis with VarSeq’s Count Alleles Algorithm

         February 25, 2020

Although VarSeq is intentionally designed to be a clinical NGS pipeline tool able to run a handful or even single samples through, we have many users who run large cohort style studies with the tool as well. One common use is to compare case/control data to isolate variants shared among affected individuals and exclude those in unaffected. One incredibly powerful… Read more »
