title: [Studies of genetic polymorphisms of ADH2 and ALDH2 among the Han population in Luoyang China].
abstract: In order to investigate genetic polymorphisms of ADH2 and ALDH2 among the Han population in Luoyang City,portions of exon 3 of ADH2 and exon 12 of ALDH gene were amplified by using polymerase chain reaction. The amplified products were electrophoresed on 10% undenatured vertical polyacrylamide gels and stained with argentine. Frequencies of ADH2*1 and ADH2*2 alleles are 42.86% and 57.14%. Frequencies of three genotypes of ADH2 are 22.86%,40.00% and 37.14%,respectively. Frequencies of ALDH2*1 and ALDH2*2 alleles are 85.24% and 14.76%. Genotype frequencies of ALDH2 loci are 71.43%,27.62% and 0.95%,respectively. Genetic polymorphisms of ADH2 and ALDH2 among the Han population in Luoyang City are different from those among Taiwanese and Shanghainese. Frequency of ALDH2*1/*1 in Luoyang people is higher than those in Shanghai and Taiwan. Therefore,there is a higher resistance to alcohol drinking in the Han population in Luoyang.
