摘要: <正> Gc(维生素D结合蛋白)的遗传多态性由Hirschfeld首次发现。用免疫电泳或聚丙稀胺凝胶园盘电泳可检查Gc三种表型:Gc1-1、Gc2-1、与Gc2-2,它们受一对等位基因Gc~1与Gc~2的控制。本文调查了四川省茂汶县羌族三种Gc表型的分布,算出其基因频率,作为羌族人群亲子鉴定的理论根据。

Abstract: Gc phenotypes were determined in sera from 317 individuals of Qiang population in Sichuan using polyacrylamide disc-electrophoresis. Three phenotypes, Gcl-1; Gc1-2; Gc2-2, were observed which was controlled by two alleles Gc~1 and Gc~2. The distribution of three phenotypes was Gc1-1 51.41%; Gc 2-1 38.49%; Gc 2-2 10.1% respectively and the gene frequencies are Gc~1 0.7066 and Gc~2 0.2934. The probability of discrimination(DP)was 0.5776. The difference of distribution of Gc phenotypes in Qiang nationality and that in Han nationality was not significant.
