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 »

Golden Helix’s End-to-End Architecture for Clinical Testing Labs

Precision Medicine and the usage of Next-Gen Sequencing to conduct genetic tests is rapidly growing. NGS based tests are increasingly used in therapeutic areas such as: Oncology Pediatrics and Newborn Screening Rare diseases There is also strong potential in areas such as diabetes and cardiac disorders, as well as in pharmacogenomics to determine safety, efficacy and cost of care. New… Read more »

Paying Attention to the Quality Fields in ExAC: A Case Study

In the past couple of weeks, the topic of the Filter and Quality fields in the popular ExAC population catalog has come up a number of times. It turns out that unlike the 1000 Genomes project, which decided to very heavily filter their variant list to only contain variants they consider high quality, ExAC chose to include more dubious variants… Read more »

NGS-based Clinical Testing eBook

This generation of scientists, clinicians and bioinformaticians have already elevated the standards for diagnosis, prediction and care, ultimately improving patient outcome for millions of people by leveraging genomic information. This trend is only going to continue. Next-gen sequencing has made its way into the clinic. Golden Helix supports the adoption of Precision Medicine by building products, such as our VarSeq… Read more »
