Supercentenarian Variant Annotation: Complex to Primitive

Mar 19, 2015

In a previous blog post, I demonstrated using VarSeq to directly analyze the whole genome sequencing data of 17 supercentenarians. Since then, I have been working with the variant set from these long-lived genomes to prepare a public data track useful for annotation and filtering. Well, we just published the…

Analyzing a Unique Family Structure in VarSeq 1.1.1

Mar 12, 2015

I am constantly on the lookout for fun or interesting datasets to analyze in SVS or VarSeq and recently came across a study looking into inherited cardiac conduction disease in an extended family (Lai et al. 2013). The researchers sequenced the exomes from five family members including three affected siblings…

Introducing Phenotype Gene Ranking in VarSeq

Mar 3, 2015

Personal genome sequencing is rapidly changing the landscape of clinical genetics. With this development also comes a new set of challenges. For example, every sequenced exome presents the clinical geneticist with thousands of variants. The job at hand is to find out which one might be responsible for the person’s illness. In…
