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 »
Yesterday, it was my pleasure to share in a live webcast our integrated solution for genetic data warehousing, VSWarehouse. If you missed the webcast live, feel free to check out the recording. Although we had a great set of questions at the end of our presentation, we didn’t have time to answer all of them, so here is a selection of… 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 »
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 »
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 »
Precision Medicine e-Book “It’s far more important to know what person the disease has than what disease the person has.” – Hippocrates (460 BC – 370 BC) Almost 2,500 years ago, Hippocrates captured one of the key principles underlying precision medicine. In the 21st century we take the understanding of the individual characteristics of a person to a new level…. Read more »
Recently, Golden Helix, Inc. announced the addition of VSPipeline to our VarSeq software suite. VSPipeline is a command-line interface that will allow high throughput environments the ability to tap the full power of VarSeq’s algorithms and flexible project template system from any command line context, including existing bioinformatics pipeline. So, what is the big deal? Here are the top five… Read more »
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 »
Today we wanted to share a recent client case study to demonstrate how VarSeq has been implemented in a CLIA certified clinical laboratory. Please feel free to contact us if you have questions or if you would like to discuss VarSeq further at info@goldenhelix.com. It is standard practice for newborns to be screened for genetic diseases before leaving the hospital to… Read more »
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 »
Regulatory Issues Regulatory bodies such as the Federal Drug Administration (FDA) already have a full plate. In the US, FDA-regulated products account for 20 percent of each dollar spent by American consumers each year. More specifically, the work of the regulatory authorities include the following: Carefully considering benefits and risks when evaluating medical products Staying on top of rapidly advancing scientific innovations… Read more »
The Educational Challenge Precision medicine will fundamentally change how health care is practiced. Of course, we have a long way to go. For most practitioners today, their knowledge of the human genome was established many years ago. However, new therapies and diagnostic methods are pouring in on a daily basis. So, how do we make sure that the current and… Read more »
Bioinformatics Pipelines and Systems Infrastructure The genetics industry is undergoing a fundamental shift from a clinical science focus to a bioinformatics focus. Genetic services require a greater level of data analytics sophistication than is required for other laboratory testing. Currently, data generated by new tests overwhelms current information technology systems and human interpretation capabilities. This is one of the reasons… Read more »
Adoption by Patients and Health Care Professionals Precision Medicine leverages the most innovative technology advances in the field of genetics. The concept is “en vouge”! We know that the science will give us increasingly better treatment options. I have covered this in my previous blog post. But does it really matter? Precision medicine only will become a reality if both… Read more »
Tailoring diagnostic and therapeutic strategies Many have called Sir William Osler (1849-1910) the “Father of Modern Medicine”. He was one of the four founding professors of Johns Hopkins Hospital where he was instrumental in creating the first residency program for the specialty training of physicians. He brought medical students from the classroom to the bedside for clinical training. He shared… Read more »
Reimbursement and Cost – Precision Medicine Part II The promise of Precision Medicine is to leverage highly targeted therapies for the benefit of the patient. By understanding better what makes us unique and leveraging our genetic make up, we hope to improve the outcome for the individual. Now, this blog is focusing on one issue that we collectively have to… Read more »
