Kaviar and Allele Frequency Aggregator (ALFA): the databases you didn’t know existed in VarSeq.

         August 4, 2020

In the search for disease causing mutations it is important to determine if the variant has been previously observed in humans and at what frequency. With the advent of increasing genomic information, there is now a variety of different databases and annotation sources that can be utilized. For some, this could be a tedious task that leads only to implementing… Read more »

Updates to Default Transcripts and Gene Preferences in VarSeq

         June 9, 2020

An under-appreciated area of complexity when looking into the field of genetics from the outside can be found in genes and transcripts. Alternative splicing allows eukaryotic species to have a wonderfully powerful genetic code, resulting in multiple protein isoforms being encoded in a single section of DNA. But when it comes to variant interpretation, different transcripts can result in widely different predicted… Read more »

Updates to ClinVar and dbSNPs: Fresh charts for Cromonaughts!

         August 28, 2014

I’m sitting in the Smithsonian Air and Space Museum basking in the incredible product of human innovation and the hard work of countless engineers. My volunteer tour guide started us off at the Wright brother’s fliers and made a point of saying it was only 65 years from lift off at Kitty Hawk to the landing of a man on the moon…. Read more »

RefSeq Genes: Updated to NCBI Provided Alignments and Why You Care

         August 14, 2014

You probably haven’t spent much time thinking about how we represent genes in a genomic reference sequence context. And by genes, I really mean transcripts since genes are just a collection of transcripts that produce the same product. But in fact, there is more complexity here than you ever really wanted to know about. Andrew Jesaitis covered some of this… Read more »
