New Assessment Catalogs Improve Saving and Tracking Variant Interpretations

         March 23, 2021

In this blog, we will be covering new assessment catalogs and how they work to improve saving and tracking variant interpretations. VarSeq is a variant analysis tool that effectively analyzes single nucleotide (SNVs) and copy number variants (CNVs) in both cancer and germline workflows.  Because VarSeq enables such diverse variant analysis, there are many research labs and institutions that evaluate… Read more »

Adding Population Catalogs to VSClinical

         December 10, 2020
example population view

Our previous webcast demonstrated some of the new functionalities of VSClinical, including the ability to add ACMG frequency sources for the ACMG BA1, BS1, and PM2 criteria. This new feature was spurred by the feedback from our users, which requested supporting frequency tracks other than gnomAD Exomes and 1kG Phase3. Now, users can implement population catalogs to VSClinical such as… Read more »

Golden Helix’s NGS-Solutions for Clinical Variant Analysis: VSClinical’s Assessment Catalog

         August 14, 2020

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 »

Using Assessment Catalogs in your VarSeq workflow

         December 15, 2016
Variant Assessment Cataloug

Variant interpretation is an integral part of any workflow that results in some decisions being made about the validity and suspected functional impact of a variant in a given sample and their presenting phenotypes. The VarSeq Assessment Catalog functionality is designed to assist the VarSeq user in streamlining this process. To include this functionality in your workflow, you will first… Read more »

Accurate Annotations: Updates to the NHLBI Exome Sequencing Project Variant Catalog

         May 19, 2015

Since its early release in early 2012, the population frequencies from the GO Exome Sequencing Project (ESP) – from the National Heart, Lung and Blood Institute (NHLBI) have been a staple of the genomic community. With the recent release of ExAC exome variant frequencies, the ESP has been surpassed as the largest cohort of publicly available variant frequencies (by nearly… Read more »

6 Population Catalogs Compared with the ExAC 61,486 Exomes

         November 13, 2014

To say the announcement of Dan MacArthur’s group’s release of the Exome Aggregation Consortium (ExAC) data was highly anticipated at ASHG 2014 would be an understatement. Basically, there were two types of talks at ASHG. Those that proceeded the official ExAC release talk and referred to it, and those that followed the talk and referred to it. Why is this… Read more »

Updates to ClinVar Curation to Include More Pathogenic Variants

         September 14, 2021

In the September 2021 monthly update to our curated ClinVar track, we made some changes that will result in roughly another 7,000 Likely Pathogenic and Pathogenic variants being available for annotation and use in the ACMG auto-classification system.  Consensus Between Labs  ClinVar has nearly one million unique variant classification records that are curated into multiple annotation tracks used in VarSeq and VSClinical on a monthly basis. Clinical… Read more »

How a neonate’s rash can be one of your most important pieces of data: making phenotypic info statistically tractable for clinical diagnostics

         August 5, 2021

I remember visiting a patient in the NICU amongst the incubators, some glowing blue like tiny tanning beds to treat jaundice, all containing tiny humans – many smaller than a loaf of bread. Infants get admitted into the neonatal intensive care unit or NICU for many reasons ranging from elevated bilirubin, hypoglycemia, sepsis, and respiratory distress (RDS). Many are eventually… Read more »

Golden Helix’s Next-Gen Sequencing Data Analysis Solutions Explained

         June 22, 2021
VSClinical algorithm

Next-gen sequencing (NGS) comprises many sophisticated steps that are often compressed into three major sections: library prep, sequencing, and data analysis. Obviously, the goal is to simplify each of these steps, but more often than not, there is a need for multiple tools to complete each one. Regarding the data analysis, Golden Helix seeks to provide simple yet comprehensive solutions… Read more »

VSPipeline Best Practices

         June 17, 2021

VSPipeline is becoming a very popular tool among VarSeq users as it is essential for creating repeatable clinical workflows that can be executed in automated fashion. Since VSPipeline is a command-line tool, I think it would be helpful to discuss some of the best practices along with helpful tips for getting the most out of VSPipeline.   Some of you may be less familiar with VSPipeline, so I want to cover how to set up the first run along with sharing the helpful tips as they arise.  … Read more »

Variant Filtration and Interpretation

         June 3, 2021

I learned about Batten disease from a childhood friend’s Facebook post. Over the course of a few months, her 8-year-old, Eva, the oldest of 4 daughters – Emily, Lucy, and Carly – was rapidly going blind. Baffled, doctors ran a genetic panel that returned a devastating result – the diagnosis of Juvenile Neuronal Ceroid Lipofuscinosis or Batten disease. A broad… Read more »

VarSeq NGS Workflow Design: Clinical vs. Research

         April 22, 2021
NGS Clinical Research

In many cases, VarSeq users design their next-gen sequencing workflows for a clinical application. One of the major values of using VarSeq is the standardization of sample analysis via project templates for filtering down to rare variants and isolate any clinically relevant variant. However, VarSeq also doubles as a robust research application as well. There are specific algorithms that can… Read more »
