Laboratory10q23 g.94645745G>A [Genotype] in Blood or Tissue by Molecular genetics method Nominal
Definition
The non-coding variant g.94645745G>A (rs12777823) located in the CYP2C cluster near the CYP2C18 gene on chromosome 10 is associated with warfarin dosing among African Americans (mainly originating from West Africa). For those with rs12777823 A/G or A/A genotypes, a warfarin dose reduction of 10-25% is recommended.[PMID: 28198005]
