By Popular Request: Our BEAGLE Algorithm Gains Support for Family Structure
by James Grover
Senior Software Engineer


Earlier this year we released our own optimized and integrated BEAGLE implementation for SVS based on the BEAGLE 4.1 and optionally 4.0 algorithms. One of the commonly requested features since that released was to expand the algorithm implementation to be considerate of the parent-offspring relationship between samples to inform and improve the accuracy of the haplotype phasing. With this information, both creating phased reference panels and the imputation of samples against those reference panels can improve in accuracy and also ensure there are no Mendelian errors in the resulting genotypes.

Updated PhoRank with OMIM Phenotype Terms and Improved Rankings
by Nathan Fortier,
Senior Software Engineer & FAS


In our latest VarSeq release, we updated our PhoRank algorithm with the ability to specify OMIM phenotype terms not present in HPO, as well as a general update to the algorithm to improve the results.

In this post, we review the fundamentals of how PhoRank determines the ranking of genes in your VarSeq projects based on your input phenotype terms (specified by project or by sample) and how our recent updates provide improved results over the original algorithmic strategy.

Genotype Imputation
Springtime for SVS: Updates to PhoRank, Platform Support and Genotype Imputation
by Gabe Rudy,
VP of Product & Engineering


Recently, we added a natively supported Genotype Phasing and Imputation capability in SNP & Variation Suite 8.7.0. Since then we have had fantastic feedback and adoption as folks take advantage of the BEAGLE 4.0 and 4.1 algorithms from within their existing SNP GWAS and agrigenomic workflows.

One piece of feedback we heard from our time at PAG, ACMG and our ongoing conversations with customers using this new capability is that when available, it would be helpful to have the imputation algorithm be aware of the known family relationship structure of the samples (i.e. the pedigree table information).

New Tutorial: VSWarehouse
by Steve Hystad,
Field Application Scientist


The new VarSeq CNV Caller Tutorial covers the basics of the VarSeq CNV calling algorithm, with an emphasis on visualization and interpretation of results. This workflow requires an active VarSeq license with the CNV Caller on Target Regions feature included. You can go to Discover VarSeq or email info@goldenhelix.com to request an evaluation license with the CNV functionality included.

Webcast: Identifying genetic variants associated with rare Mendelian Diseases
May 3, 2017
Guest: Dr Jingga Inlora


Dr. Jingga Inlora is a postdoctoral fellow in the Snyder lab at Stanford University. In this webcast, Inlora will present on her team's recent study focused on identifying genetic variants associated with rare Mendelian Diseases.

Recent advances in next-generation sequencing (NGS) technologies have brought a paradigm shift in how researchers investigate common and rare diseases. While whole genome sequencing remains costly, whole exome sequencing (WES) is less expensive and has recently been introduced into clinical practices such as disease treatment, screening and prenatal diagnosis.

This month featured two terrific webcasts. Dr. Reza Sailani from Standord University kicked off the month off with a terrific overview of two studies on Whole Exome Sequencing at his lab. This was followed by an indepth overview of our improved CNV capabilities by Dr. Nathan Fortier. We are always excited to host events like this for our community. Each webcasts had hundreds of registrations from researchers and clinicians around the globe. Now, we have closed on a new and exciting strategic partnership. This will be announced next week, so stay tuned!

CNV Analysis in Varseq - A User's Perspective

Clinical labs must have the ability to go from a collection of samples to a professional report documenting a short list of clinically relevant variants and copy number variants. Copy number variants (CNVs) in particular play an important role in human health and disease, and the detection of CNVs in clinical samples has the potential to improve clinical diagnoses and inform treatment decisions. The VarSeq CNV Algorithm (VS-CNV) has been developed to help facilitate this analysis in a single algorithm that can be run in conjunction with your variant analysis. In this webinar, we will discuss the typical CNV workflow from a VarSeq user's perspective. Watch here.

P.S. Here is some Q&A from the webcast you can read here!

   Customer Success
Several of our customers have published recently using our SVS software, and I wanted to share their work with you. Congrats to all! Here are some of the highlights:
