作者用聚丙烯酰胺凝胶平板电泳法,对我国人群尿淀粉酶同工酶谱进行分离检测时,有98%左右的人群尿中出现正常型酶谱,仅有少数人检出异型(0.48%)和显型(1.45%) 。异型和显型出现频率在群体遗传学上,种族间有显著差异,我国北方各民族也呈现程度不同的差异。对检出的异型和显型进行遗传学分析时,均与家族遗传有关,通过家族系谱调查,均属于常染色体显性遗传,并对身体健康无显 The author used polyacrylamide gel electrophoresis to separate the urine amylase isoenzymes in our country, and 98% of the normal urine samples were found in normal urinary samples. Only a few of them showed abnormal (0.48% ) And phenotype (1.45%). There are significant differences in genotypes and phenotype frequency between groups in population genetics, and the differences among ethnic groups in northern China also show different degrees. The detected abnormalities and phenotypes for genetic analysis, are related to family heredity, family pedigree investigation, are autosomal dominant, and no significant physical health
