In a recent webcast, users were exposed to some new features upcoming in the next release of VarSeq. In this update, we will use an example de Novo CNV in a cardiomyopathy panel in VarSeq. There is a long list of new tools and polishes to the software but one major upgrade is the inclusion of the ACMG and ClinGen… Read more »
Our previous webcast from VP Gabe Rudy in September exposed us to some fundamentals of this years’ updated Technical standards for the interpretation and reporting of constitutional copy-number variants: a joint consensus recommendation of the American College of Medical Genetics and Genomics (ACMG) and the Clinical Genome Resource (ClinGen). This recent webcast was dedicated to breaking down these new guidelines… Read more »
Typically, researchers are looking for rare variants in their next generation sequencing datasets. However, most of the nonsynonymous variants have unknown significance because there is an inherent difficulty in validating large numbers of rare variants or even detecting rare variants with high statistical power. In lieu of this issue, computational tools are needed as they accurately predict the pathogenicity of… Read more »
A common discussion with our customers includes the challenges with the tertiary stage of analyzing next-gen sequencing data. This is the stage where all data from gene panels, exome, or whole genome scale pass through filters to quickly isolate the clinically relevant variant contributing to a patient disorder. Golden Helix has recognized these challenges in the scale of data and… Read more »
As the world is consumed by the ongoing pandemic, it is easy to forget that there are investigators all around the globe that continue to make important discoveries in human medicine. Below are a few examples that remind us there are those that persevere in their chosen fields of study despite the trying times. At Golden Helix, we continue to… Read more »
Did you know you can control your preferred transcript settings for clinical interpretation in VSClinical? Your lab is analyzing the DNA of a tissue sample from a patient with small cell lung cancer. The lab technician has imported the patient data into VSClinical to detect clinically relevant variants and evaluate and score these according to the AMP Guidelines, as well… Read more »
In this blog update, I’ll be walking you through some of the advanced plotting capabilities with GenomeBrowse. The strategy with any next-gen sequencing analysis is to filter down to interesting variants for either research or clinical conclusion. Golden Helix produces powerful software specifically tailored for this efficient and comprehensive search for interesting and clinically relevant variants. One additional advantage of… Read more »
VSClinical is a feature to evaluate clinically relevant variants according to the ACMG or AMP guidelines. This feature can also be used to identify if a variant has been observed previously or evaluate a manually inserted variant. Take, for example, the scenario where a colleague is interested to see if you have seen any variants associated with Bechet syndrome, which… Read more »
In our recent webcast announcing the upcoming release of VarSeq VSClinical and the implementation of the ACMG guidelines for NGS CNVs, we had a number of live questions we didn’t get a chance to cover at the end of the presentation. I will follow up on those questions in this blog post. But first, if you didn’t get a chance to join us for… Read more »
We would like to thank everyone who participated in our 2020 t-shirt design competition. It was great to see the amount of creativity our community expressed and was certainly a tough decision to make! We are pleased to announce this year’s winners: First Place – Michaela Lucas Michaela Lucas is a senior graphic design student at The Pennsylvania State University…. Read more »
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 »
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 »
SVS 8.9.0 was released on August 19th and features a new GBLUP by Bin feature and a new utility to find the LD scores of markers and categorize them into bins, along with several mixed-model upgrades and many other upgrades, fixes, and polishes. The two new features LD Score Computation and Binning and Compute GBLUP Using Bins, while they can… Read more »
Our software solutions and partners have brought dramatic improvements to the secondary and tertiary analysis stages of variant evaluation. Regarding secondary analysis, we’ve discussed increased efficiencies in speed and overall accuracy in the variant calling process with Sentieon. On the tertiary side, we have explored numerous workflows in VarSeq highlighting filtration to clinically relevant variants, as well as the automated… Read more »
The detection and interpretation of Copy Number Variants (CNVs) is vital for the clinical evaluation of individuals with a wide range of disorders. Golden Helix has remained at the forefront of CNVs in Next-Gen Sequencing (NGS) data since 2016 with the release of VS-CNV, our solution that allows you to both detect and analyze CNVs directly from NGS data. Earlier… Read more »
This morning I released a new version of my eBook “Genetic Data Warehousing – Second Edition.” As Next-Generation Sequencing is taking off in the clinic, it creates a significant data management issue for clinicians, scientists, and IT professionals alike. How can we retain the massive amounts of data coming out of clinical pipelines in a way that enables labs to… Read more »
It doesn’t take much effort to find articles discussing the value of Next-Generation Sequencing (NGS). There is a consistent tone amongst authors that implementing NGS pipelines are critical for clinical efficiency in both hereditary disorders and somatic. However, NGS strategies do not come without their own challenges. Challenges include not only the detection and calling of high quality/probability variants from… Read more »
