OMIM Coming to VarSeq

         September 1, 2015

When it comes to down to it, the genomic variants we collect in a research and clinical setting are impossible to interpret without that important link of how genes are related to phenotypes. Indisputably, the Johns Hopkins project to catalog all evidence related to inheritable Mendelian diseases is our best repository of this evidence. Online Mendelian Inheritance in Man (OMIM)… Read more »

Between Two Bases: Coordinate Representations for Describing Variants

         August 27, 2015

Have you ever scratched your head when looking up a variant and it seems like the number you have for its position is one off from what it looks like in the file or database? You may be running into the dreaded world of 1-based versus 0-based coordinate representation! If it’s any consolation, I can promise that all the bioinformaticians… Read more »

Coverage Statistics Come to VarSeq

         August 20, 2015

A prerequisite for clinical NGS interpretation is ensuring that the data being analyzed is of high enough quality to support the test results being returned to the physician. The keystone of this quality control process is coverage analysis. Coverage analysis has two distinct parts. Ensure that there is sufficient coverage to be confident in called variants Make certain that no… Read more »

Comparing Variants using a Venn Diagram

         July 7, 2015
annotate

One of the lesser known functions in SVS allows the user to create Venn diagrams comparing variants found in multiple spreadsheets. These different spreadsheets could come from individuals samples, a case vs. control group or several variant databases. It is a helpful tool for visually comparing different variants. Start by creating spreadsheets for each group/samples you’d like to compare. The… Read more »

The Clinical Genome Conference 2015 Highlights

         June 30, 2015

This last week I had the pleasure of attending the fourth annual Clinical Genome Conference (TCGC) in Japantown, San Francisco and kicking off the conference by teaching a short course on Personal Genomics Variant Analysis and Interpretation. Some highlights of the conference from my perspective: Talking about clinical genomics is no longer a wonder-fest of individual case studies, but a… Read more »

Just a few weeks ago we announced our partnership with MedGenome. The news was covered by a number of outlets including: Financial Express Pharmabiz Let me expIain the importance and impact of this announcement. Since Varseq was released, we have received strong interest from testing labs that are leveraging our product to implement cancer diagnostic pipelines. Please feel free to take… Read more »

Frequently Asked Questions about VarSeq

         June 16, 2015

The support team at Golden Helix is always on-hand to help with your SVS and VarSeq needs. We get some questions more often than others, and this blog will answer some of the most common questions we’ve been seeing lately regarding VarSeq. A common question we receive is if data can be filtered from a locally kept set of variants… Read more »

VarSeq is a better ANNOVAR, snpEff and VEP

         June 9, 2015

Yes, I said it. “Them be fighting words” you may say. Well, it’s worth putting a stake in the ground when you have worked hard to have a claim worth staking. We have explored the landscape, surveyed the ravines and dangerous cliffs, laboriously removed the boulders and even dynamited a few tree stumps. Stake planted. Ok, so now I’m going… Read more »

Looking Beyond the Exons: Splice Altering Variants

         June 5, 2015

There are many approaches that one might use to define a variant as potentially deleterious. For example, we often see analysis workflows based on rare, non-synonymous variants, perhaps incorporating additional annotation sources that capture known or predicted consequences of coding variants. Annotations for coding regions of the genome are relatively abundant and familiar to genome scientists. We are comfortable in… Read more »

What’s in a Name: The Intricacies of Identifying Variants

         May 26, 2015

There’s a strong desire in the genetics community for a set of canonical transcripts. It’s a completely understandable and reasonable thing to want since it would simplify many aspects of analysis and especially the downstream communicating and reporting of variants. Unfortunately, biology isn’t so tidy as to provide a clear answer for which transcript is the important one. Consequently, there… Read more »

Unique Labs, Common Tool: Making VarSeq Ready for Clinical Workflows

         April 9, 2015

As VarSeq has been evaluated and chosen by more and more clinical labs, I have come to respect how unique each lab’s analytical use cases are. Different labs may specialize in cancer therapy management, specific hereditary disorders, focused gene panels or whole exomes. Some may expect to spend just minutes validating the analytics and the presence or absence of well-characterized… Read more »

Are Cancer Gene Panels just another stepping stone on the way to… Read more »

Analyzing a Unique Family Structure in VarSeq 1.1.1

         March 12, 2015

I am constantly on the lookout for fun or interesting datasets to analyze in SVS or VarSeq and recently came across a study looking into inherited cardiac conduction disease in an extended family (Lai et al. 2013). The researchers sequenced the exomes from five family members including three affected siblings and their unaffected mother and an unaffected child of one… Read more »
