In the previous blog post, we covered the automated steps to create a VarSeq project. Today we will examine the active analysis steps. These are the steps that require human interpretation to analyze the clinically relevant variants. A lab tech can take the first pass at the output in the generated VarSeq project. They can perform the quality control and… Read more »
Automating a clinical workflow creates a stable and repeatable clinical analysis. Automation reduces the potential to introduce human error, helps in regulatory compliance, and improves the precision of the clinical results. It is important to know that if you run a sample through your clinical pipeline, you are going to get the same results today as you will in 6… Read more »

Mark Trinder is an MD/Ph.D. student at the University of British Columbia, Canada working under the supervision of Dr. Liam Bruham. Mark’s research focuses on… Read more »
Examples of Clinical Variant Interpretation with VSClinical In this chapter, I’d like to go through a few examples for variants that have been classified with the help of VSClinical. This will give you a better understanding of how data sources are actually being represented in the software and how those are used to make decisions on applicable criteria. It goes… Read more »
Clinical Variant Analysis – Classification Criteria of Benign Variants The classification of benign variants is overall simpler and more straightforward, with the majority of benign variants being eliminated through allele frequency in various population catalogs. BA1 If a variant is common in one or more population catalog, as indicated by the allele frequency associated by the appropriate sub-population, it can… Read more »
We would like to thank everyone who entered our 2019 Abstract Competition. This event is an excellent opportunity for our team to hear the unique ways Golden Helix software is being applied around the world. We had a number of remarkable entries this year which made our selection process a daunting one, indeed. It is my pleasure to announce this… Read more »
Clinical Variant Analysis – Applying ACMG Guidelines to Analyze Germline Diseases The clinical interpretation of genetic variants is time-consuming and requires strict attention to detail. Clinicians must thoroughly review any variants that could potentially cause disease using a complex set of guidelines. There are guidelines for the interpretation of variants relating to hereditary risk, germline diagnostics issued by the American… Read more »
This blog will conclude our VSClinical Best Practice Workflow series and focuses on one of our new reports: VSClinical ACMG Gene Panel Template. This template is valuable because it automatically enters your variant interpretation from the ACMG Guidelines into the report and eliminates the need for manual submission. I would like to explain how to properly implement this report into… Read more »
In part one of this series, we discussed how the ACMG Classifier can be implemented in your filter chain to support a best practice workflow. To continue our discussion on best practices of VSClinical, this blog will shed light on other attributes of VSClinical that can add support to your evaluation. Specifically, we will explore how VSClinical can help users… Read more »
VarSeq Stable 2.1.0 is Ready for Clinical Validation, See it in Action Next Week This week we are happy to see the general availability of VarSeq 2.1, the culmination of the last five months of work since we launched VSClinical. We have been blown away by the adoption of VSClinical, outpacing any previous product launch in terms of the pace… Read more »
In the first two parts of this blog, we presented examples of how to leverage Warehouse-stored VSClinical and CNV assessment catalogs in the VarSeq project. Now we are going to explore the Warehouse interface a bit more and show how to query on stored variant data. To access Warehouse from VarSeq, click the V Connect icon located in the top… Read more »
We recently hosted a webcast covering the value and application of VSWarehouse through VarSeq. Not only is VSWarehouse a solution for storing your NGS data in a central repository, but it also provides a means to enhance the tertiary analysis done in VarSeq. VSWarehouse will store all your sample/variant data but also stores your catalogs of pathogenic variants, clinical reports, and has the capability of filtering/querying on all your stored data quickly. In addition,… Read more »
This webcast generated some great questions! If you have any other questions for me that are not answered below, please feel free to ask those by emailing [email protected]. To what level does the Warehouse scale? We have tested multiple instances of Warehouse in-house and on the cloud and it scales incredibly well to tens of thousands of samples and 100s… Read more »
In my recent webcast, I demonstrated how VS-CNV users can detect high-quality copy number variant events. If you didn’t have a chance to join, you can view the recording below! This webcast generated a lot of great questions! If you have any other questions about the content covered in this webcast that is not answered below, please feel free to… Read more »
Genome-wide association studies (GWAS) are useful in genetics as they test for the association of a phenotype with common genetic variants. GWAS is “hypothesis-free” and does not require prior knowledge of a gene’s biological impact on a trait. The catch though is that this leads to analyzing hundreds to thousands of genome-wide array samples to elucidate single nucleotide polymorphisms (SNPs) associated with a specific phenotype.
Our “Processing Hereditary Cancer Panels in VarSeq” webcast was a great lesson for viewers to learn more about the functionality of our software. If you didn’t have a chance to join us for the live event, you can watch the recording on our site here. Q: What is the best place to get clinical interpretations of breast cancer variant interpretations?… Read more »
Are you curious how others are taking advantage of Golden Helix software to further their research and findings? Well, look no further, here’s a few of our customer’s publications for you to check out.
With this two-part blog series, users should now be able to perform CNV analysis using their data, set up basic quality filter standards to isolate high-quality events and utilize annotations to hone in on publicly known events as well as in-house recorded CNVs from previous projects.
If we take a look back in time, a lot happened in September 1998. It is the month in which the first ever “Who wants to be a Millionaire?” show debuted on ITV in Britain. Larry Page and Sergey Brin incorporated Google in September, registering the Google.com domain on September 15, 1998. And on that very same day, we officially… Read more »
The recent release of VSClinical gives users the ability to evaluate variants based on the 33 criteria according to the American College of Medical Genetic and Genomics (ACMG) guidelines. This feature leverages a variety of variant sequencing evidence including population data, functional data, and computational predictions while providing rich visualizations and auto recommendations to help answer challenging criteria. This highly… Read more »
