As our team returns from another successful ASHG conference, I would like to reflect on the great memories, connections, and future plans that were made at this meeting. First, I will start by thanking everyone involved with the superb planning and execution of the conference. We are thankful to have this opportunity to connect with our customers, partners, and friends… Read more »
The common approaches to detecting copy number variants (CNVs) are chromosomal microarray and MLPA. However, both options increase analysis time, per sample costs, and are limited to the size of CNV events that can be detected. VarSeq’s CNV caller, on the other hand, allows users to detect CNVs from the coverage profile stored in the BAM file, which allows you… Read more »
Before examining the clinical evidence associated with a specific mutation, a clinician must establish that the variant is likely to be a driver mutation which generates functional changes that enhance tumor cell proliferation. Our recent blog series “Following the AMP Guidelines with VSClinical” briefly mentioned how the oncogenicity scoring system in VSClinical could be used to automate and assist the… Read more »
From diagnosing, treating and preventing diseases in humans and animals, to preserving our global food supply, Golden Helix products are being used all over the world! In September, we were cited in many publications spanning a diverse range of species and topics. Below are brief recaps of a few of the studies where SNP & Variation Suite (SVS) and VarSeq… Read more »
Customers are always asking for ways to improve their experience with Sentieon, our partner’s secondary analysis tools that process genomics data with high computing efficiency, fast turnaround time, exceptional accuracy and 100% consistency. We have a few tips to get the most out of Sentieon. In this article I will be going over: Basic system requirements Custom scripts vs default… Read more »
Gene Fusion Background Gene fusions are hybrid genes that result from translocations, interstitial deletions, or chromosomal inversions that can lead to constitutive gene activation and result in increased or abnormal protein production. Increased or abnormal protein production subsequently can play an important role in tumorigenesis and thus identifying and evaluating this type of biomarker is important in the cancer workspace….

We have covered a lot of ground in this Automating & Standardizing Your Workflows blog series. First, we saw how to perform secondary analysis with Sentieon to generate the necessary VCF and BAM files for tertiary analysis in Part I. The implementation of VSPipeline allowed for rapid import and project generation for a predefined cancer gene panel project template in… Read more »
VSClinical users can interpret and report genomic mutations in cancer following the AMP guidelines which we’re demonstrating in this “Following the AMP Guidelines with VSClinical” blog series. Part I introduced the hands-on analysis steps involved in creating a high-quality clinical report for targeted Next-Generation Sequencing (NGS) assays. We reviewed sample and variant quality, including the depth of coverage over the target regions by the sequencing performed for each sample. Now, we are ready to… Read more »
In our last part of this series, we showed how to run a pre-built workflow template via VSPipeline to automatically import and filter sample variants to streamline the search for clinically relevant variants. Now, we can deep-dive into our filtered, pathogenic variants to fully understand and capture their final classification and interpretation. Filtered Germline Variants for ACMG Guidelines The VSPipeline… Read more »
VSPipeline: Automating your Tertiary Workflows The first part of this “Automating & Standardizing your NGS Workflow” blog series covered the secondary analysis steps of read alignment and variant calling with Sentieon. The next step is to transition into the tertiary analysis via utilization of our workflow automation tool, VSPipeline. VSPipeline operates as a command-line tool meant to simplify the deployment… Read more »
We are always excited to see how our software is used to support research and enable precision medicine. We believe that our customer’s success is ultimately our success! This summer was filled with many wonderful publications from across the globe and we are proud to have been a part of them. Here are just a few from each month: June… Read more »
In the world of genomics shaping precision medicine in oncology, the limiting factor is the time-to-sign-out of a fully interpreted molecular profile report. There are many components of the entire testing process that add to the turn-around time of each test. Many of these steps, such as sample prep, sequencing, and automated secondary analysis, are bounded and consistent in their time requirements. The hands-on… Read more »
With the increasing knowledge of mutations involved in cancer, it is imperative to have a tertiary analysis pipeline that provides users with the most up to date information on somatic mutations. VSClinical’s Cancer Add-On does just that and more; with this feature, users can investigate and report on SNVs, indels, CNVs, gene fusions, and considerations for wild type genes in… Read more »
Earlier this week, Inc. magazine ranked Golden Helix on the 2019 Inc. 5000 list with three-year revenue growth of 61%. The Inc. 5000 list represents a unique look at the most successful companies within the American economy’s most dynamic segment—its independent small businesses. Microsoft, Dell, Domino’s Pizza, Pandora, Timberland, LinkedIn, Yelp, Zillow, and many other well-known names gained their first… Read more »
Huntington’s Disease (HD) Background Huntington’s Disease (HD) is an autosomal dominant neurodegenerative disease that is caused by a mutation in the huntingtin (HTT) gene resulting in 36 or more CAG trinucleotide repeats in exon 1. Individuals affected by HD experience motor disorders including involuntary movements and poor coordination, cognitive impairments showing a decline in thinking and reasoning and psychiatric disorders… Read more »
Secondary Analysis with Sentieon: Rapid and Accurate Variant Calling This blog post will cover the utilization of secondary analysis tools to produce a list of high-quality variants and associated coverage data. This data will serve as the main, importable content for the tertiary stage of analysis where variants are interpreted and classified for their impact on a patients’ disorder. We… Read more »
As our regular customers may know, we write our blogs to provide relevant content to any NGS-based analysis with VarSeq. Our goal here at Golden Helix is to provide top quality software and guidance on how to use the software efficiently to perform variant analysis. However, this blog series will take a more general perspective and supply some insight into… Read more »
Congenital Myasthenic Syndromes (CMS) History: Congenital Myasthenic Syndromes (CMS) are a group of rare hereditary conditions that can cause seizures, severe muscle weakness, respiratory problems, and potentially disabling weaknesses shortly after birth or early childhood (1). CMS is the result of abnormalities in acetylcholine proteins residing in the motor endplate of the neuromuscular junction (1). These abnormalities can be diagnosed… Read more »
When using VarSeq; annotations, application settings, and assessment catalogs are all stored locally. Sometimes these resources can grow to large space grabbing directories, causing you to either purchase additional storage devices or getting rid of previously downloaded resources you might need down the road. But there’s hope! You can set where you want all of your data stored to be… Read more »
