title: [HLA-A, B, and DRB1 gene polymorphisms in Mongol ethnic group of Inner Mongolia, China].
abstract: We investigated the genetic polymorphisms of HLA-A, B, DRB1 alleles and haplotype frequencies in Mongols from Inner Mongolia, China. A PCR-based reverse line-strip sequence specific oligonucleotide hybridization method was used to determine the alleles of HLA-A, B, DRB1 in 106 unrelated, healthy Mongol individuals of Inner Mongolia. Allelic and haplotype frequencies of these loci were calculated by the maximum likelihood estimator method. Altogether, 13 HLA-A alleles, 29 HLA-B alleles and 13 HLA-DRB1 alleles were observed in the population. The most frequent HLA A-B, B-DRB1, and A-B-DRB1 haplotypes were HLA-A*02-B*46 (0.0510), HLA-A*02-B*13 (0.0495), HLA-A*02-B*51 (0.0442); HLA-B*13-DRB1*07(0.0555), HLA B*46-DRB1*09 (0.0378), HLA-B*35-DRB1*13(0.033); and HLA-A*02-B*13- DRB1*07(0.033019), HLA-A*02-B*46-DRB1*09 (0.031985), respectively. These results indicated that the HLA loci are highly polymorphic in Mongols of Inner Mongolia, and haplotypes HLA-A*24-B*14, HLA-A*32-B*63 have significant linkage disequilibrium.
