Abstract:
OBJECTIVETo elucidate the genotype distribution of HLA-DRB1 polymorphisms in the Han race population in Liaoning of China and to evaluate its value on forensic medicine.
METHODSThe blood DNA samples from 13265 unrelated Chinese individuals of Han race population in Liaoning province were investigated and HLA-DRB1 alleles were genotyped with PCR-SSP and PCR-SSOP in low resolution level.
RESULTSThirteen HLA-A alleles were found, in which HLA-DRB1*15, 09, 12, 07 were the commonest but HLA-DRB1*03(18), HLA-DRB1*14(8) were absent. The population data conformed to the Hardy-Weinberg equilibrium(chi-square was 73.34, df was 78, P> 0.5). The exclusion probability of paternity was 64.7%, the power of discrimination was 97.9% and the heterozygosity was 89.4%.
CONCLUSIONThe HLA-DRB1 polymorphism of Liaoning Han populations show the special characters and HLA-DRB1 genotyping is useful genetic marker to paternity testing and personal identification.
