VarSeq PhoRank Part: 2 Sample PhoRank Gene Ranking

The PhoRank tool in VarSeq is further explored in this post by looking at the sample-specific capability. VarSeq PhoRank Part: 1 Variant Phorank Gene Ranking showed how the PhoRank algorithm could be applied to all the variants in a VarSeq project, regardless of the number of (or difference in) samples. There is another PhoRank algorithm in VarSeq that allows the… Read more »

VarSeq PhoRank Part 1: Variant PhoRank Gene Ranking

One of the main goals of clinical genomic labs is to identify problematic variants in affected individuals. One tool to assist in this search is the phenotype driven variant ontological re-ranking tool in VarSeq called PhoRank. A common situation facing clinicians is sorting through thousands of variants provided by an individual’s exome data (or possibly the individual’s nuclear family exome… Read more »

Our Philosophy on Quality in Product Testing and Development

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 »

The SVS 8.8.3 release was created to incorporate some of the CNV, genome assembly control, and splice site capabilities that are present in VarSeq, as well as clean up and streamline the GWAS workflows (like when using Mixed Linear Model algorithms) for a better user experience. New Product Add-Ons for SVS GoldenHelix SVS now includes in-silico splice site, functional prediction… Read more »

Using the GRCh38 Reference Assembly for Clinical Interpretation in VSClinical – Webcast Recap

VCF file format

Even though GRCh37 is currently the most widely used human genome assembly, GRCh38 provides a more complete human reference genome, offers more accurate genomic analysis, and includes centromere and mitochondrial information. However, we’re getting ahead of ourselves. Perhaps start with how we got here. The Human Genome Project started this all off with the world’s largest biological collaboration project in… Read more »
