广东汉族人细胞色素C242T p22phox基因多态性观察

C242T p22phox gene polymorphism in the population of Han nationality in Guangdong province

目的调查广东汉族人是否存在细胞色素C242T p22phox基因多态性。方法应用聚合酶链反应-限制性长度多态性法(PCR-RFLP)检测122名广东籍汉族人C242T p22phox基因多态性。结果CC基因型频率为0.877,CT+TT基因型频率为0.123,C等位基因频率为0.934,T等位基因频率为0.066。结论广东汉族人存在C242T p22phox基因多态性,该基因多态性存在种族差异。

This study aimed to investigate the gene polymorphism of the C242T p22phox in the population of Han nationality in Guangdong Province by randomly selecting 122 unrelated healthy candidates examined by means of polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). It was found that the C and T allele frequencies were 0.934 and 0.066, and CC and CT+TT genotype frequencies were 0.877 and 0.123, respectively, in the population of Han nationality in Guangdong Province, suggesting the presence of C242T p22phox gene polymorphism with significant racial differences.
