To recap what we have covered in this blog series thus far, Sentieon allows users to call somatic variants against a matched normal sample and a tumor-only analysis. Part I of this series covered the variant calling workflow for tumors with matching normal samples. However, a common situation would be to call variants for a tumor sample without the normal….

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 »
Happy New Year. I trust you had a relaxing time over the holidays with family and friends as well as a great start into 2019. Golden Helix certainly had a landmark year. There were many highlights that actually shaped the direction for us in the years to come. Please let me mention a few: We launched VSClinical in May 2018:… Read more »
High product quality is a foundational characteristic of a useful and successful product. Quality testing, therefore, is a necessary, albeit an open-ended task. It can at times seem a limitless undertaking in the present using experience from the past to improve the future. Nonetheless, it is approached as a development stage at Golden Helix that is just as essential as… Read more »

Celebrating our 20th Anniversary on September 15th, we took some time to reflect on the last two decades in this industry. Two decades of learning, adaption, and growth on the business side as well as the personal side. Employees began their careers with us, made new friends and started their own families. These past 20 years are full of stories… Read more »
If we take a look back in time, a lot happened in September 1998. It is the month in which the first ever “Who wants to be a Millionaire?” show debuted on ITV in Britain. Larry Page and Sergey Brin incorporated Google in September, registering the Google.com domain on September 15, 1998. And on that very same day, we officially… Read more »
In the last installment of this series, I covered the basics of variant interpretation and how it fits into the genomic testing process. Now we can cover in more detail how VSClinical works, what algorithms and annotation sources power the recommendations and how the ACMG criteria are organized into useful categories. VSClinical is built to make the process of evaluating… Read more »
Yesterday we launched VSClincial with our first webcast in what will be a series about this powerful new way to perform variant interpretation following the ACMG guidelines. In this post, I wanted to cover the motivation for VSClinical and how we curated and presented the 33 criteria from the ACMG Guidelines into an intuitive workflow with various bioinformatic evidence and… Read more »
First-place Abstract Competition Winner, Michael Iacocca, shared his research with the Golden Helix Community during our February webcast ‘Using NGS to detect CNVs in familial hypercholesterolemia‘. In this webcast, he gave a great explanation on how our CNV caller aided his team in their research. If you were unable to join us for the event, you can find a recording… Read more »

2017 was an incredibly prosperous year for Golden Helix; we released a handful of new features, announced new partnerships and completed our end-to-end architecture for clinical testing labs. Our webcast series has become a very popular way for our community to stay up-to-date with our new capabilities and best practices in genetic analysis using our software. We had three webcast… Read more »
The Golden Helix SNP & Variation Suite (SVS) platform is a powerful and versatile set of tools and algorithms for performing genomic research. That research spans from data originating on genotype micro-arrays to next-generation sequencing. While the majority of SVS users start with genotype data on their samples, any genomic information across a cohort can be used in our various… Read more »
First of all, I wish you a prosperous 2018 along with happiness and health for you and your loved ones. This next year comes with lots of anticipation. We at Golden Helix are looking forward to another year of growth and innovation. Over the last few years, we were able to build a large following of clients in the clinical space…. Read more »
As VarSeq is quickly becoming the go-to variant analysis software for tertiary analysis, we want to give our readers the opportunity to examine completed projects from start to finish. As an addition to the currently available demonstration projects, we are pleased to provide users with a Single Exome Analysis example project. To access this project simply click here to download… Read more »
Clinical Assessment Tracks Golden Helix provides a large catalog of annotation sources for our research and clinical clientele. Making these public data repositories available to all our users is no easy task. As Cody Sarrazin mentioned in his blog post, annotation curation is a complex data science pipeline. This process aggregates data from many disparate sources and normalizes it into… Read more »
Next-Gen Sequencing promised to be the ultimate paradigm when it comes to genetic research and clinical testing since it contains the complete genetic information. When it comes to the current reality in testing labs, there are still a number of additional testing paradigms used in an analysis, specifically, copy number variations. Among these, labs still widely use Chromosomal Microarrays and… Read more »
An Example of an Integrated Clinical Workflow for CNVs and SNVs In this blog series, I discuss the architecture of a state of the art secondary pipeline that is able to detect single nucleotide variations (SNVs) and copy number variations (CNVs) in one test leveraging next-gen sequencing. In Part I, we reviewed genetic variation in humans and looked at the key… Read more »
Examples of CNV Calling What do CNV calls actually look like? What are some of the key metrics to determine an event? Part IV of the Secondary Analysis 2.0 blog series will answer these questions by walking through some examples of how our CNV caller, VS-CNV, identifies CNVs. Golden Helix integrates multiple metrics to determine if a CNV event is… Read more »
Detection of CNVs in NGS Data Our Secondary Analysis 2.0 blog series continues with Part III: Detection of CNVs in NGS Data. We will give you an overview of some design principles of a CNV analytics framework for next-gen sequencing data. There are a number of different approaches to CNV detection. The published algorithms share common strategies to solve the… Read more »
