Notes

PharmGKB indicates that this SNP is relevant to Warfarin dosing. rs339097(G) is associated with 14.5% higher therapeutic warfarin dose in African Americans. This variant is also more common in African Americans with minor allele frequencies of 11–14% , but only 0.2% in Caucasians. Genetic and nongenetic factors associated with warfarin dose requirements in Egyptian patients.
