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 »
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 »

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 »
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 »
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 »
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 »
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 »
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 »
Dear All, Going back in time to the beginning of this year, it would have been difficult to imagine what our world would look like as of June 2020. Things changed quickly. While we are still in the midst of the COVID-19 pandemic, the senseless killing of George Floyd triggered social unrest here in the USA that points to deeper… Read more »
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 »
Thank you to everyone who joined me for yesterday’s webcast, I hope you all enjoyed it. If you missed the live event and are interested in knowing what we talked about, good news, you can watch the recorded version right here! There were so many great questions asked during our Live Q&A that I was unable to answer all of… Read more »
Introducing Drugs & Trials for Cancer Diagnostics VSClinical offers enormous simplicity and consistency in evaluating biomarkers and providing treatment options. Last month, we announced our newest feature to now include the automated collection of relevant clinical trials. The new capability was unveiled in our “Introducing Drugs & Trials for Cancer Diagnostics” webcast with Nathan Fortier, Ph.D., Director of Research, showing… Read more »
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 »
Happy New Year! Certainly, I hope you had a relaxing time over the holidays with family and friends as well as a great start into the new year. 2019 was a real landmark year for Golden Helix. Please let me mention a few highlights: We launched VSClinical AMP in June 2019: This product is supporting the clinical variant interpretation based… Read more »
As clinical genetic tests have been adopted as a critical enabler of precision medicine, the number of tests offered by clinical labs and the volume of tested patients has grown by orders of magnitude in the past five years. The Gene Testing Registry, managed by the NIH, documented a rise from 13,000 to 60,000 tests offered in the US market… Read more »
The first two blogs in this series covered Sentieon’s somatic variant calling from Tumor with Normal (Part I) and Tumor without Normal (Part II). In addition to providing multiple somatic variant calling processes, users also have access to high-sensitivity scripts and full support for the GRCh38 reference assembly. Without going into excessive detail, this final blog of the series will… Read more »
To recap what we have covered in this blog series thus far, Sentieon allows users to call somatic variants against a matched normal sample and a tumor-only analysis. Part I of this series covered the variant calling workflow for tumors with matching normal samples. However, a common situation would be to call variants for a tumor sample without the normal….

As I mentioned in the first part of this series, Sentieon allows users to call somatic variants against a matched normal sample and a tumor-only analysis. Utilization of a Tumor-Normal Workflow In addition to the fundamental process of alignment and variant calling, there are a few more steps that will improve the quality of your secondary analysis. Figure 1 (below)… Read more »
