腺苷脱氨酶在我国九个民族中的多态分布

用沉粉胶电泳及特异染色的方法,对我国九个少数民族中红细胞腺苷脱氨酶(ADA)的多态分布进行了测定。ADA2基因频率在白族中最高(0.0735),土家族中最低(0.0300),二者差异显著。白族及土家族与其它民族(维吾尔0.0654、彝族0.0622、回族0.0610、藏族0.0547、满族0.0485、侗族0.0450、苗族0.0320)比较,差异均不显著。没有发现罕见表型。

ADA POLYMORPHISM IN NINE ETHNIC GROUPS OF CHINA

Using the starch gel electrophoresis and specific staining, we analysed the ADA polymor-phism of nine ethnic groups in China. The highest frequency of ADA2 gene was found in the Bai ethnic group (0.0735), and the lowest in the Tujia (0.0300). There was a significant difference between them. The frequencies of ADA2 in the Uygur, Yi, Hui, Tibetan, Manzu, Dong, Miao ethnic groups were 0.0654, 0.0622, 0.0610, 0.0547, 0.0485, 0.0450, 0.0320, respec-tively. There was no significant difference among them, and with those of Bai and Tujia ethnic groups.
