Abstract

Samples from 635 unrelated Japanese blood doners in Tokyo were examined for their red cell uridine monophosphate kinase phenotypes using starch gel electrophoresis. Three phenotypes were found: UMPK1 (570, 89.76%), UMPK 2--1 (63, 9.92%) and UMPK 2 (2, 0.32%). The corresponding gene frequency for UMPK1 was 0.9472 and for UMPK2 was 0.0528. The UMPK2 frequency in the present study was slightly higher than the previously reported value for Caucasians in the United States, but the difference is not statistically significant. A study of 15 twin pairs and their parents was in agreement with the hypothesis of autosomal codominant inheritance for UMPK.

摘要

利用淀粉凝胶电泳,对东京635名无亲缘关系的日本献血者的样本进行了红细胞尿苷单磷酸激酶表型检测。发现了三种表型:UMPK1(570例,占89.76%)、UMPK 2--1(63例,占9.92%)和UMPK 2(2例,占0.32%)。UMPK1的相应基因频率为0.9472,UMPK2的相应基因频率为0.0528。本研究中UMPK2的频率略高于此前报道的美国白种人的频率,但差异无统计学意义。对15对双胞胎及其父母的研究结果与UMPK的常染色体共显性遗传假说相符。
