Secondary Analysis 2.0 – Part IV

Detection of CNVs

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 »

Secondary Analysis 2.0 – Part III

Detection of CNVs

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 »

Secondary Analysis 2.0 – Part II

Detection of CNVs

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 »

Secondary Analysis 2.0 – Part I

Detection of CNVs

Human genetic variation makes us unique. On average, humans are to 99.9% similar to each other. Understanding in detail what the nature of the difference in our genetic make-up is all about allows us to assess health risks, and eventually enables Precision Medicine as we determine treatment choices. Furthermore, it enables scientists to better understand ancient human migrations. It gives… Read more »

CNV exome analysis coming to VarSeq!

CNV Exome Analysis

VarSeq will soon provide CNV exome analysis! In our webcast last week, we announced that we took our CNV caller, VS-CNV, to the next level. Along with the ability to call CNVs at the single-exon level in NGS gene panels, VarSeq can soon be used to call large loss of heterozygosity (LOH) and  CNV events at the exome level. The combination… Read more »
