During the webcast yesterday, I demonstrated a few ways of customizing de Novo Candidate and Compound Heterozygous Candidate workflows to consider family structure that was slightly different from the default trio workflow. The families included additional affected and unaffected siblings added to a trio as well as looking at what could be done if there were only two affected siblings… Read more »
Submit directly to N-of-One from VarSeq If you or your lab uses N-of-One solutions for clinical annotations, here’s some good news: You can now submit directly to N-of-One from VarSeq! N-of-One’s set of preferred transcripts may differ from those outputted by our algorithms in VarSeq, so our solution was built with that in mind. Our slick, easy to use, and… Read more »
Wednesday, May 11th 12:00 pm EDT VarSeq contains default workflows for Trio analysis which include filter chains for identifying de Novo and Compound Heterozygous variants, but what if you have data for a full Quad or even just a few siblings? How could your VarSeq workflow be adjusted to handle this custom family structure?In this presentation we will demonstrate how… Read more »
Benjamin Darbro, MD, PhD at the University of Iowa, uses VarSeq® software for Clinical Testing Founded by Hans Zellweger in the 1960’s, The Shivanand R. Patil Cytogenetics and Molecular Lab at the University of Iowa has a long history of clinical testing, seeing 45 years of advancements. Today, the lab is mainly focused on oncology, pre and post-natal genetics testing… Read more »
Wednesday, March 2nd 12:00 pm EST Clinical labs must have the ability to go from a collection of samples and associated variants to a professional report documenting a short list of clinically relevant variants. Cancer Gene Panels are a common clinical application for genetic tests. In this webcast we will show how VarSeq and VSReports can be used to go… Read more »
As VarSeq continues its adoption amongst clinical labs and researchers looking for reproducible workflows for variant annotation, filtering and interpretation, we have continued to prioritize the addition of features to assess the quality of the upstream data at a variant, coverage and now sample level. The Importance of Quality Assurance Sample prep and sequencing problems are difficult to detect through the analysis… Read more »
Scaling is in our DNA: Making Genomics Accessible One of the things I absolutely love about the work we do at Golden Helix is keeping up with the changes in data analysis driven by the iterative and generational leaps in technology. But one thing has always been a constant since day one: we break preconceived notions of what scale of… Read more »
Genetic Data Warehousing e-Book In our webcast last week, we announced the upcoming release of VSWarehouse, a scalable genetic data warehouse for VarSeq. Genetic data warehousing becomes more important as Next-Generation Sequencing is taking off in the clinic, creating significant data management issues for clinicians, scientists and IT professionals alike. How can we retain the massive amounts of data coming out… Read more »
Compound Heterozygous Workflows: Including a 2nd Affected Child Looking for Compound Heterozygous regions for a trio is fairly straight forward in VarSeq, we include this workflow in our shipped Exome Trio Template. An example of which is included with our Example Projects which can be found by going to File > Example Projects > Example YRI Exome Trio Analysis. But… Read more »
So, why are we launching a new data warehouse product? Why did we build VSWarehouse? According to Grand View Market Research, the next generation sequencing (NGS) market size was $2.0 billion (USD) globally in 2014. This number is expected to grow from 2015 to 2022 at an annual rate of about 40%. What drives this phenomenon is the increasing number… Read more »
Golden Helix in 2016 We had a terrific year 2015. It was the year in which we got serious about the clinical testing market. We successfully continued on the path of attracting more referenceable clients such as University of Iowa, Baby Genes, Prevention Genetics and many more. We rounded out our VarSeq suite by adding more clinically relevant features and… Read more »
The most common use of the VarSeq Match Gene List algorithm of course is to determine if the variants in your data set are contained within your genes of interest. As an example of this, say you are working with a whole exome trio and only want to consider those variants that are contained within the 56 genes recommended by… Read more »
Probably one our most popular public annotation sources we curate and update is the database of Non-Synonymous Functional Predictions (dbNSFP). In it’s recent update, it has expanded the predictions to include FATHMM-MKL and VarSeq now incorporates this new prediction into its voting algorithm of now 6 different discrete predictions per variant. You can update to dbNSFP 3.0 using the built-in… Read more »
As VarSeq’s adoption has grown among analysts using whole exome data to diagnose rare diseases, a couple of family designs outside of the common trio of an affected child and both parents have come up frequently. While having both parents provides the maximum power to discover de novo mutations and recessively inherited variants, it is not always possible to contact… Read more »
With the release of VarSeq 1.3.1 we have included a new demo project to showcase a single tumor-normal pair analysis workflow. The project can be accessed through VarSeq and VarSeq Viewer by going to File > Open Example Projects > Example Tumor-Normal Pair Analysis. This project contains an exome pair (Normal-N990005 and Tumor-T990005) from the Gastric Cancer study Exome sequencing of… Read more »
With the release of VSReports, we added the ability to “select” rows of your filtered output (often variants, but potentially things like coverage regions or genes) with a new feature dubbed “Record Sets”, but more often described as “colored checkboxes” for your tables. Although necessary for the important task of marking primary, secondary or other sets of variants for a… Read more »
As VarSeq gains in popularity, we want to give Viewers and customers alike the opportunity to look at projects that are completed from start to finish. To this end, VarSeq (and VarSeq Viewer!) currently comes with two demonstration projects, Example TruSight Cardio Gene Panel and Example YRI Exome Trio Analysis. To access these projects from the VarSeq start page go to… Read more »
Our webcast yesterday featured two clinical workflows and and the ease in moving from an unfiltered variant file to a clinical report containing the variants of interest using VarSeq and VSReports. There were several great questions and I wanted to pass on a few of particular interest. Question: Are annotation sources included in VarSeq for free?
While VarSeq comes with a number of starter workflows that are stored as templates, customers also have the option of creating filter chains from scratch; analyzing a single exome may require you to do exactly that. In this blog, I’ll go through analyzing a single exome and generating a list of variants for further study. After importing the variant data… Read more »
The 65th annual ASHG in Baltimore will be another exciting one. We at Golden Helix have been very busy this year making great improvements to both SVS and the VarSeq software and we look forward to showcasing them during our in-booth demos. In particular, we will launch two new additions to the VarSeq software suite; VSReports and VSWarehouse. VSReports brings highly customizable clinical… Read more »
