What You Need to Know About Staging Annotations

         January 22, 2021

Annotating genomic variants is a very complex process but perhaps the most important part of next-generation sequencing variant analysis. Here at Golden Helix, we recognize the importance and value of having the most up-to-date sources available and curating new annotation sources as they become available for variant analysis. Golden Helix has curated over 100 annotation sources for human variant analysis… Read more »

VSClinical: Defining Sample Phenotypes
