The last tip of the week I did was Genome Variation Tour I where we started our journey following one SNP in an individual’s genome through various databases to see what we can find out about that variation. In that tip we started out by looking at a SNP in the CYP4F2 gene in the UCSC Genome Browser and followed it to dbSNP. Today’s tip will continue our journey to OMIM to see what information we can find there. We’ll find this variation is clinically associated with Warfarin dosage effects and specifically this individual’s C/T heterozygosity indicates an intermediate dosage for effectiveness if indeed he ever needed this drug. In some ways, your guess is as good as mine as to what we will find and what avenues we will be taking in the next few tips I’ll be doing. I’m am discovering information as I go along too. I can tell you though that the next installment of the genome variation tour will take us to PubMed, and a few not particularly well known but gem databases perhaps and probably back to the UCSC Genome Browser to expand our look at the interactions of several variations in this individuals genome.
