目的:探讨细胞色素P4502C19(CYP2C19)在维吾尔族、汉族冠心病人群中的基因型及等位基因分布特征,并考察年龄对其基因多态性的影响。方法:选择355例(维族194例、汉族161例)无亲缘关系的冠心病患者,采用多聚酶链反应-限制性片段长度多态性(PCR-RFLP)法分析维、汉族 CYP2C19基因特征,并比较两族不同年龄组(<60岁和≥60岁)基因多态性的差异。结果:与汉族患者比较,维族患者等位基因*1显著增加[(64.9%比75.2%),P<0.01],等位基因*2(29.5%比22.2%)和等位基因*3(5.6%比2.6%)频率显著降低(P均<0.05),;基因型*1/*1显著增加[(38.5%比57.7%),P<0.01],*1/*2显著降低[(44.7%比31.5%),P<0.05],其他4基因型两族无显著差异(P>0.05);快代谢型频率(38.5%比57.7%)显著增加,中代谢型(52.8%比31.5%)显著降低(P均<0.01);同一民族中,年龄对其基因型及等位基因分布差异无显著影响(P均>0.05)。结论:维、汉族冠心病患者细胞色素 P4502C19基因型及等位基因分布有显著不同,了解其特征对指导临床用药,改善患者预后具有重要意义。

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 (<60 years and≥60 years)of the tWo nationalities.Results:Compared With Han na-tionality patients,there Were significant increase in allele*1 frequency [(64.9% vs.75.2%),P<0.01],signifi-cant decrease in allele*2 (29.5% vs.22.2%),and allele*3 (5.6% vs.2.6%) frequencies (P<0.05 all);geno-type*1/*1 significant increase [(38.5% vs. 57.7%),P<0.01],*1/*2 significant decrease [(44.7% vs. 31.5%),P<0.05],and other four genotype betWeen tWo nationalities Were no significant difference (P>0.05);fast metabolic patter frequency (38.5% vs. 57.7%)significant increase,moderate metabolic patter frequency (52.8% vs. 31.5%)significant decrease (P<0.01 all)in Uighur nationality patients ;In a same nationality,age had no significant impact on its genotype and allele distribution (P>0.05 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.
