  • Influence of CYP2C9 *3, VKORC1-1639 G>A and CYP4F2 rs2108622 Genetic Polymorphisms on Warfarin Dosage

    Objective To investigate the influence of CYP2C9 3,VKORC1-1639 G>A and CYP4F2 rs2108622 genetic polymorphisms on warfarin dosages of patients after heart valve replacement. Methods A total of 133 patients undergoing heart valve replacement in the Department of Cardiovascular Surgery of Fujian Provincial Hospital from November 2011 to August 2012 were included in this study. Polymerase chain reaction(PCR)gene sequencing was performed to detect CYP2C9 3,VKORC1-1639 G>A and CYP4F2 rs2108622 genetic polymorphism of these 133 patients. Patients were grouped according to their genotypes,and average warfarin dosages were compared between different genotype groups. Results The frequencies of CYP2C9 3 AA,AC and CC were 127 patients,6 patients and 0 patient respectively,and average daily warfarin dosages were 3.75 mg and 2.13 mg respectively which were statistically different between differentCYP2C9 3 genotypes (P<0.05). The frequencies of VKORC1-1639 G>A GG,GA and AA were 3 patients,32 patientsand 98 patients respectively,and average daily warfarin dosages were 6.00 mg,4.50 mg and 3.00 mg respectively which were statistically different between different VKORC1-1639 G>A genotypes (P<0.05). The frequencies of CYP4F2 rs 2108622 CC,CT and TT were 67 patients,59 patients and 7 patients respectively,and average daily warfarin dosages were 3.00 mg,3.75 mg and 4.50 mg respectively which were statistically different between different CYP4F2 rs2108622 genotypes(P<0.05). Conclusion CYP2C9 3,VKORC1-1639 G>A and CYP4F2 rs2108622 genetic polymorphisms are associated with individual difference of warfarin dosages of patients after heart valve replacement.
