摘要: 目的 比较中国汉族与蒙族健康人群细胞色素氧化酶 CYP2C19 遗传多态性 。方法 应用限制性片段长度多态性分析法(PCR-RFLP),对 74 名汉族健康志愿者和 6 名蒙族健康志愿者进行基因多态性分析 。结果 蒙族中基因型为野生型纯合子wt/wt 的发生率为 16.7% (1/6),汉族中发生率为 41.9%(31/74);蒙族基因型为杂合子 wt/m1 和 wt/m2 的为50%(3/6),汉族中为 45.9%(34/74);蒙族基因型为突变型纯合子 m1/m1 和 m1/m2 的为 33.3%(2/6),汉族中为 12.2%(9/74)。本实验未发现 m2/m2基因型。结论 在中国蒙族和汉族受试者中,wt/wt 和m1/m1的发生率没有显著差别。中国蒙族和汉族健康人群细胞色素氧化酶 CYP2C19 遗传多态性未显示出统计学差别。

Abstract: AIM: To compare genotypePolymorphism of cytochrome CYP2C19 between Chinese Meng subjects and Chinese Han subjects.METHODS: The genotypePolymorphism was analyzed byPCR-RFLP(Restriction FragmentlengthPolymorphism)in 74 subjects of healthy Chinese Han and 6 subjects of Chinese Meng.RE-SULTS: Of the 74 genotyped healthy subjects,31(41.9%)were homozygous for wildtype (wt/wt),9(12.2%)were homozygous for CYP2C19m1 and CYP2C19m2 (m1/m1 or m1/m2 or m2/m2),and 34(45.9%)were heterozygous for CYP2C19m1 or CYP2C19m2 (m1/wt or m2/wt).Among the 6 genotyped Chinese Meng,1 (16.7%)was homozygous for wildtype(wt/wt),2 (33.3%)were homozygous for mutant allele CYP2C19m1 and CYP2C19m2 (m1/m1 or m1/m2 or m2/m2),and 3(50.0%)were heterozygous for CYP2C19m1 or CYP2C19m2 (m1/wt or m2/wt);no homozygousgeno-type for CYP2C19m2(m2/m2)was found in this study.CONCLUSION: There is no statistical difference in oc-currence of wt/wt and m1/m1 between in 74 subjects of healthy Chinese Han and 6 subjects of Chinese Meng.
