93197-2
LaboratoryCYP4F2 gene c.1297G>A [Genotype] in Blood or Tissue by Molecular genetics method Nominal
Definition
The presence of the CYP4F2*3 (rs2108622) allele indicates that a patient who self-identifies as being of non-African ancestry may require a slightly increased warfarin dose than predicted by CYP2C9/VKORC1 alone.[PMID: 18250228] The rs2108622 variant (c.1297G>A) results in an amino acid substitution (valine to methionine) at position 433 (p.V433M).
