  • Order vs observation: Observation
  • Method: Molgen

What it does not mean

  • The code identifies the observation or test, not the actual result.

Key facts

CYP4F2 gene c.1297G>A [Genotype] in Blood or Tissue by Molecular genetics method Nominal
CYP4F2 gene.c.1297G>A
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.[PMID18250228] The rs2108622 variant (c.1297G>A) results in an amino acid substitution (valine to methionine) at position 433 (p.V433M).
