Customizing VSClinical Reports with New Output Types

         September 23, 2021

Golden Helix VSClinical provides a guided workflow interface for following the ACMG and AMP guidelines to evaluate variants and CNVs for NGS tests. The output of this work is most often a lab-specific clinical report. Since it was introduced, we have provided a powerful Word-based templating system to allow labs to customize reports to include specific content and branding. Recently… Read more »

Merging VCFs in an Imperfect World

         September 7, 2021

Merging variant records across samples is important when performing trio or family analysis as it ensures that hereditary relationships can be properly inferred. There are many ways to represent a single variant. Insertions and deletions may be right or left aligned, prefixes and suffixes can be added, and adjacent variants in the same sample may be combined or split at… Read more »

Manage gene lists across projects with VarSeq and VSClinical

         August 18, 2021

Clinical labs often maintain gene panels, which are lists of genes with evidence of disease association. These panels are used to prioritize variants and limit interpretations to a predefined set of test-specific genes. In general, gene panels should be stored independently of any specific project or interpretation, as it is common for an individual gene panel to be generally applicable… Read more »

Customer Publications in July 2021

         July 29, 2021

In this month’s Customer Publication blog, I will highlight four studies that provided further insights into conditions that are typically identified in early childhood.

Leveraging expert-curated variant interpretations using VSClinical

         July 27, 2021
Clinical Genome Resource

This blog post will cover an exciting new VSClinical feature in the upcoming VarSeq release. The ACMG Previously Interpreted Variants feature allows users to integrate databases of expert-curated variant interpretations into their VSClinical workflows. These data sources store variant-level interpretation data, including the classification, associated disorders, interpretation text, and scored criteria for each variant, along with notes providing a justification… Read more »

Selecting Clinically Relevant Transcripts in VarSeq

         June 28, 2021

One of the many tricks of encoding so much functionality into so little space in eukaryotic genomes is the ability to produce multiple distinct mRNAs (transcripts) from a single gene. While one transcript is often the dominant one for a given tissue or cell type, there are, of course, exceptions in the messy reality of biology. It doesn’t take many… 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 »

Harmonizing Next-Generation Sequencing Data: VarSeq Liftover Tool

         June 15, 2021
genomeAsia

One of the inherent realities of next-generation sequencing is the ongoing updates to the human reference genome—one of the strongest recommendations to take the original sequencing data and remap to the latest genome assembly. However, there are several reasons why remapping may be impractical. So, an alternative solution is needed to convert the data running through an initial mapping to… Read more »

A Simple Guide to Curating Genome Assemblies

         June 8, 2021
curate

A common feature request from Golden Helix customers is to curate and make available genome assemblies for different plant and animal species. These requests commonly come from SVS users as many research projects are being carried out, and having the genome assembly available for analysis is essential. That being said, Golden Helix has an SVS Tutorial available that walks users… Read more »
