Golden Helix is in a unique position to provide a secure on-premise analysis solution. This capability is based on two enablers. First, we build our software solutions from scratch and from the ground-up with the assumption that it should run on any operating system and potentially behind firewalls or even without internet access. Second, we provide these solutions on a licensing model based on training and supporting users, not… Read more »

These templates are tailored for various applications including tumor-normal, trios, cancer and hereditary gene panels, and ACMG Guidelines workflows. The templates contain application-specific annotation sources and algorithms that will automatically load into… Read more »
Customizing VSClinical ACMG Guidelines Workflow Part 2 In the first part of this series, we covered how VarSeq provides customization of the clinical analysis workflow process. VSClinical’s various customization parameters within the ACMG Guidelines workflow includes the choice of how the internal knowledge base of previous variant interpretations are stored and what considerations go into this choice. In this blog, we… Read more »
Hospitals and testing labs are undergoing a digital transformation like any other business in our time. They deal with personal data in categories with the highest level of security requirements: personal identity and medical records. The architecture chosen to store and analyze this data is critical to provide the best protection against a data breach incident. The liability and institutional… Read more »
When interpreting a variant using the AMP/ASCO guidelines for somatic variant interpretation, clinicians must determine whether the variant can be considered a biomarker that affects clinical care by predicting sensitivity, resistance, or toxicity to a specific therapy. Such a determination requires the investigation of multiple evidence sources, including clinical trials, FDA approved therapies and peer-reviewed studies. Unfortunately, strong evidence linking… Read more »
Clinical labs offer a unique and sophisticated product that is performed repeatedly with high standards of quality. VarSeq was developed to provide labs with the customization required for clinical genetic tests in a repeatable workflow. On top of this, VSClinical offers additional parameters and choices that can be made when designing the test workflow. In this blog series, we will… Read more »
Genetic testing labs deal with personal data in categories with the highest level of security requirements: personal identity and medical records. Given the liability and risk associated with a breach of this secure information, it is not surprising that many labs and institutes that aggregate genomic data prefer, if not require, on-premise analysis and storage solutions. Golden Helix is in… Read more »
As clinical genetic tests have been adopted as a critical enabler of precision medicine, the number of tests offered by clinical labs and the volume of tested patients has grown by orders of magnitude in the past five years. The Gene Testing Registry, managed by the NIH, documented a rise from 13,000 to 60,000 tests offered in the US market… Read more »
The first two blogs in this series covered Sentieon’s somatic variant calling from Tumor with Normal (Part I) and Tumor without Normal (Part II). In addition to providing multiple somatic variant calling processes, users also have access to high-sensitivity scripts and full support for the GRCh38 reference assembly. Without going into excessive detail, this final blog of the series will… Read more »
Our team has returned from the annual meeting of the Association of Molecular Pathology (AMP 2019), and, as always, I am grateful for all the wonderful experiences we are bringing back with us. The plenary sessions and talks were bountiful, and we were very impressed with the well-organized exhibition. Hats off to everyone involved in planning this great event! Innovation… Read more »
We have recently added a tutorial to help introduce customers to the ease and utility of the AMP Guidelines incorporated in VarSeq’s VSClinical package. The AMP Guidelines allow users to sort through available clinical evidence in a streamlined fashion to arrive at final classification and interpretation and then transfer that information into a clinical report. And the AMP Guidelines also… Read more »
As I mentioned in the first part of this series, Sentieon allows users to call somatic variants against a matched normal sample and a tumor-only analysis. Utilization of a Tumor-Normal Workflow In addition to the fundamental process of alignment and variant calling, there are a few more steps that will improve the quality of your secondary analysis. Figure 1 (below)… Read more »
This month’s webcast delves into VSWarehouse with a focus on our new capability of storing somatic variant projects and catalogs built for the AMP Guidelines within VSClinical. If you didn’t have a chance to join us for the live event, please enjoy the video recording below. Previous webcasts have gone into great detail on the features and processing of somatic… Read more »
The Golden Helix team is excited to be headed to Baltimore for the AMP 2019 Meeting, and we hope to see you there! You will find our team at booth #2856. Swing by or schedule a time to talk with us one on one about how Golden Helix’s platform is redefining next-gen sequencing analysis. Our team would love to hear… Read more »
VarSeq 2.2.0 was released today and this a stable release full of upgrades and polishes. Some of the newer features include the ability to store and include AMP Cancer assessment catalogs on VSWarehouse, quicker accessibility to common annotations plotted in GenomeBrowse, and the addition of all of our standard templates for the GRCh38 genome assembly. Many of the polishes were… Read more »
As our team returns from another successful ASHG conference, I would like to reflect on the great memories, connections, and future plans that were made at this meeting. First, I will start by thanking everyone involved with the superb planning and execution of the conference. We are thankful to have this opportunity to connect with our customers, partners, and friends… Read more »
The common approaches to detecting copy number variants (CNVs) are chromosomal microarray and MLPA. However, both options increase analysis time, per sample costs, and are limited to the size of CNV events that can be detected. VarSeq’s CNV caller, on the other hand, allows users to detect CNVs from the coverage profile stored in the BAM file, which allows you… Read more »
Gene Fusion Background Gene fusions are hybrid genes that result from translocations, interstitial deletions, or chromosomal inversions that can lead to constitutive gene activation and result in increased or abnormal protein production. Increased or abnormal protein production subsequently can play an important role in tumorigenesis and thus identifying and evaluating this type of biomarker is important in the cancer workspace….

We have covered a lot of ground in this Automating & Standardizing Your Workflows blog series. First, we saw how to perform secondary analysis with Sentieon to generate the necessary VCF and BAM files for tertiary analysis in Part I. The implementation of VSPipeline allowed for rapid import and project generation for a predefined cancer gene panel project template in… Read more »
VSClinical users can interpret and report genomic mutations in cancer following the AMP guidelines which we’re demonstrating in this “Following the AMP Guidelines with VSClinical” blog series. Part I introduced the hands-on analysis steps involved in creating a high-quality clinical report for targeted Next-Generation Sequencing (NGS) assays. We reviewed sample and variant quality, including the depth of coverage over the target regions by the sequencing performed for each sample. Now, we are ready to… Read more »
