September 27, 2017 12:00 PM, EDT While Copy Number Variants are important to detect and interpret in many clinical genetic tests, labs have been without a comprehensive solution that integrates the annotating and reporting of high-quality CNV alongside their existing NGS variants. Golden Helix has developed and validated with our clinical partners a specialized NGS-based CNV caller capable of detecting… 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 »
In this blog series, I will discuss the architecture of a state of the art secondary pipeline that is able to detect single nucleotide variations (SNV) and copy number variations (CNV) in one test leveraging next-gen sequencing. In Part I, we reviewed genetic variation in humans in general and looked at the key components of a systems architecture supporting this… Read more »
In case you missed our live event yesterday, I wanted to share the Q&A session and a link to the webcast recording: An Exploration of Clinical Workflows in VarSeq. Question:You mentioned saving projects as templates, will it save GenomeBrowse plots in the project template or do you have to replot the data when opening the software? Answer: Yes, if you save your… Read more »
The current reduced cost and increase availability of genome sequencing has been making academics, clinicians and individuals alike excited with the possibility of increased research depth, diagnosing capability and personal curiosity. And although a freshly sequenced genome is chock-full of tasty letter snippets, the real revelation and education occurs when comparing to an annotation foundation. In this post, I’ll review… Read more »
Yesterday’s monthly webcast featured our end-to-end solution for clinical labs. In case you missed it, you can watch the webcast here! There were a number of questions asked in the live event, so in today’s blog post I wanted to recap the Q&A session. Can you go over the requirements for the CNV algorithm in more detail? If you are… Read more »
We are back from another exciting trip to ESHG, hosted in Copenhagen, Denmark last week. We were delighted by the number of researchers and clinicians we were able to connect with. Needless to say, the weather was outstanding in Copenhagen, which made our stay even more pleasant! Even though this was a European event, it was great to be able to speak with… Read more »

This partnership will integrate Sentieon’s secondary analysis tools with Golden Helix software to provide users with a comprehensive solution for genomic data analysis. Sentieon’s suite of secondary analysis tools made the significant improvement in runtime over BWA-MEM, GATK,… Read more »
Last week was fast and furious for those of us who made it to Phoenix attending ACMG 2017. The event was exceptionally well attended, with great talks and sessions. Here are some of the highlights that are worth mentioning from our perspective. Numerous talks referenced how important the updated Exac/gnomAD database is for clinical NGS analysis. The new dataset includes… Read more »

While the temps have been mostly mild for the last few weeks in Montana, I bet those of you in the northeast are looking forward to your time in Phoenix! You will find… Read more »
Just as we expected, 2017 has kicked off with a flurry of new publications by our customers. We even had a publication from a client using our VarSeq software! Congratulations to all, please take a look at some of the articles we have highlighted below: Reza Sailani of Stanford University and colleagues published Association of AHSG with alopecia and mental retardation… Read more »
It’s hard to believe that summer has already faded into fall and that ASHG 2016 is right around the corner! 2016 has been quite a busy year for us so far at Golden Helix. We have been working hard to bring our community the very best tools available for variant interpretation and SNP analysis. This year at ASHG, you can… Read more »
After the Wet Lab process has been completed, the bioinformatics analysis of the sequencing data work begins. The next three blogs will focus on three aspects of this process. The building blocks of a bioinformatics pipeline, documentation and validation (today’s topic) Quality Management Clinical Reporting The Building Blocks of an NGS PipelineThe bioinformatics process to analyze NGS data occurs in three… Read more »
As spring ends and summer begins here in Montana, we wanted to share another round of customer publications. It’s so important to us that our software plays a role in our client’s success, and we love to display the fruit of their hard efforts each month.
