摘　　要： 目的　考察性别对中国汉族人群细胞色素氧化酶CYP2C19遗传多态性的影响。方法　应用限制性片段长度多态性分析法 (PCR RFLP)对 14 0名男性和女性中国健康志愿者进行了基因多态性分析。结果　男性中基因型为野生型纯合子wt mt占 4 4 2 3% (2 3 5 2 ) ,基因型为杂合子wt m1和wt m2占 4 4 2 3% (2 3 5 2 ) ,基因型为突变型纯合子m1 m1和m1 m2占 11 5 4 % (6 5 2 ) ;而女性中基因型为野生型纯合子wt wt占 35 2 3% (31 88) ,基因型为杂合子wt m1和wt m2占 5 0 0 % (44 88) ,基因型为突变型纯合子m1 m1和m1 m2占 14 82 % (13 88)。在本实验中未发现m2 m2基因型。结论　在中国男性和女性受试者中 ,wt wt和m1 m1的发生率无显著差别。性别对中国汉族人群细胞色素氧化酶CYP2C19遗传多态性的影响在统计学上无差别。 Aim To assess the effect of gender on genetic polymorphism of cytochrome CYP2C19 in Chinese population. Methods The genetic polymorphism of 140 healthy Chinese were analysed by PCR-RFLP (restriction fragment length polymorphism). Results Of 52 genotyped male subjects, 23 (44.23%) were homozygous for wildtype (wt/wt), 6 (11.54%) were homozygous for CYP2C19 m1 (m1/m1), and 23 (44.23%) were heterozygous for CYP2C19 m1 or CYP2C19 m2 (wt/m1 or wt/m2); and among the 88 genotyped female subjects, 31 (35.23%) were homozygous for wildtype (wt/wt), 13 (14.82%) were homozygous for CYP2C19 m1 (m1/m1), and 44 (50.0%) were heterozygous for CYP2C19 m1 or CYP2C19 m2 (wt/m1 or wt/m2); no homozygous genotype for CYP2C19 m2 (m2/m2) was found in the study. Conclusion There is no statistical difference in ocurance of wt/wt and m1/m1 between in male and in female, so gender have no significant effect on genetic polymorphism of cytochrome CYP2C19.
