ABSTRACT
Objective:To explore the genotype and allele distribution feature of cytochrome P450 2C19 (CYP2C19) in Uighur and Han nationality patients With coronary heart disease (CHD).Methods:A total of 355 CHD patients Without kinship,including 194 Uighur cases and 161 Han cases,Were selected. CYP2C19 genetic polymorphism Was analyzed using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP),it’ s compared betWeen different age groups (0.05);fast metabolic patter frequency (38.5% vs. 57.7%)significant increase,moderate metabolic patter frequency (52.8% vs. 31.5%)significant decrease (P0.05 all).Conclusion:There are significant differences in cytochrome P450 2C19 genotype and allele distribution betWeen Uighur nationality and Han nationali-ty CHD patients,Understanding those is of important significance to guide clinical medication and improve patients' prognosis.
