广东地区汉族人群的hGSTP1Ile105Val基因多态性的研究

Genetic polymorphism of human glutathione S-transferase P1 gene among the Han nationality in Guangdong province

目的 :对广东地区汉族人群的hGSTP1Ile10 5Val基因多态性进行研究。方法 :应用PCR -RFLP(基因体外扩增限制性片段长度多态性分析 )的技术方法进行研究。结果 :该人群中GSTP1基因在 10 5位点的野生型纯合子 (AA)基因型的分布频率为 5 7.4 % ,突变型纯合子 (GG)基因型为 6 .7% ,杂合子 (AG)基因型为 35 .9%。结论 :GSTP1纯合突变基因型在广东地区汉族人群中的分布频率为 6 .7%。

AIM: To analyse the frequencies of individuals of the GSTP1 genotypes among the Han nationality in Guangdong province. METHODS: Polymerase chain reaction-restriction fragment length polymorphism was taken to analyse the GSTP1 genotypes and identify the gene frequencies. RESULTS: The proportion of AA(Ile/Ile),AG(Ile/Val) and GG(Val/Val) genotypes were 57 4%,35 9% and 6 7%, respectively. CONCLUSION: The frequencies of individuals carrying homozygous of the GSTP1 variant allele were 6.7% among the Han nationality in Guangdong province.
