摘要: 目的与方法:以PCR - RFL P 技术对上海郊县“本地人”人群GSTP1 基因型多态性进行了研究。结果:该人群中GSTP1基因1578 位点野生型纯合子Ile105/ Ile105 (AA) 基因型频率为63. 9 % ,突变型纯合子Val105/ Val105( GG) 基因型为1. 2 %杂合子Ile105/ Val105(AG) 基因型为34. 9 %; Ile105 及Val105 两种等位基因的频率分别为0. 813 及0. 187 。以上情况与已报道的高加索人种和非洲裔美国人的情况有明显差异,而与同为中国人群的其它地域(北京、台湾) 居民人群频率分布特征基本一致。结论:中国人群内部在hGSTP1 基因A1578G位点上的多态性情况表现高度均一。

Abstract: Purpose and Methods : Population polymorphism at the locus of A1578G of human glutathione S -t ransferase P1 gene in an“Indigenous”Shanghainese group were investigated by PCR - RFL P approach. Results : The data showed that the population f requencies of genotypes Ile105/ Ile105 (AA) , Val105/ Val105 ( GG) and Ile105/ Val105 (AG) were 63. 9 % ,1. 2 % , 34. 9 % , respectively. Allele f requencies of Ile105 and Val105 were detected as 0. 813 and 0. 187 , respectively. The situation differs significantly f rom that of several Caucasian populations and Af rican Americans reported. Conclusion : Among different sub - population ( resident groups dist ributing in different areas) of Chinese population , GSTP1 A1578G locus proved to be of highly homogenous on the aspect s of allele f requency.
