西安交通大学学报(英文版)(2005)
摘要
Objective To analyze the genetic polymorphism of 6 STR loci (D12S358, D12S1675, D12S1663, D12S1697, D12S1725 and D12S1613) on chromosome 12 in Chinese Han population. Methods EDTA-blood specimens were collected from 153 unrelated individuals of Chinese Han population in Shaanxi province. Allele and genotype frequencies for the 6 STR loci were estimated and statistical parameters of polymorphism were calculated. Results 8 alleles and 18 genotypes, 10 alleles and 17 genotypes, 9 alleles and 15 genotypes, 12alleles and 29 genotypes, 12 alleles and 31 genotypes, 8 alleles and 11 genotypes were observed at D12S358, D12S1675, D12S1663, D12S1697, D12S1725 and D12S1613, respectively. No deviations of the observed allele frequency from Hardy-weinberg equilibrium expectations were found for any of these loci. The Heterozygotes of these 6 loci were 78.89%, 66.10%, 54.95%, 79.10%, 71.98% and 59.48%, respectively. It indicated the high genetic polymorphism of the loci in Chinese Han population. Conclusion The 6 STR loci belonged to the genetic marker system of high discriminutesation and high information in Chinese Han population and can be used in the study of gene-related diseases.
