摘　　要：采用聚合酶链式反应 限制性片段长度多态性 (PCR RFLP)方法测定酒精脱氢酶 2 (ADH2 )和乙醛脱氢酶 2 (ALDH2 )的基因型 ,以获得ADH2、ALDH2基因多态型在中国汉、回、蒙古、维吾尔、白五个民族正常人群样本中的分布并对其进行比较。结果显示 :(1)五民族中均为杂合型ADH2与纯合型ALDH2占优势 ;(2 )ADH2。Genotypes of alcohol dehydrogenase 2(ADH2) and aldehyde dehydrogenase 2(ALDH2) were detected by using polymerase chain reaction restriction fragment length polymorphism (PCR RFLP) in order to acquire and compare the distributions of polymorphisms about ADH2 and ALDH2 in five Chinese nationalities. The results were as follows: (1) Heterozygous genotype of ADH2 and homozygous genotype of ALDH2 are the two dominant ones in all the five nationalities. (2) The distributions of the two genes 'polymorphisms have certain differences among some nationalities.
