Analysis of high-resolution HLA-A, -B, -Cw, -DRB1, and -DQB1 alleles and haplotypes in 718 Chinese marrow donors based on donor-recipient confirmatory typings.
High-resolution human leucocyte antigen (HLA)-A, -B, -Cw, -DRB1, and -DQB1 alleles and haplotype frequencies were analysed from 718 Chinese healthy donors selected from the Chinese Marrow Donor Program registry based on HLA donor-recipient confirmatory typings. A total of 28 HLA-A, 61 HLA-B, 30 HLA-Cw, 40 HLA-DRB1 and 18 HLA-DQB1 alleles were identified, and HLA-A*1101, A*2402, A*0201, B*4001, Cw*0702, Cw*0102, Cw*0304, DRB1*0901, DRB1*1501, DQB1*0301, DQB1*0303 and DQB1*0601 were found with frequencies higher than 10% in this study population. Multiple-locus haplotype analysis by the maximum-likelihood method revealed 45 A-B, 38 Cw-B, 47 B-DRB1, 29 DRB1-DQB1, 24 A-B-DRB1, 38 A-Cw-B, 23 A-Cw-B-DRB1, 33 Cw-B-DRB1-DQB1 and 22 A-Cw-B-DRB1-DQB1 haplotypes with frequencies >0.5%. The most common two-, three-, four- and five-locus haplotypes in this population were: A*0207-B*4601 (7.34%), Cw*0102-B*4601 (8.71%), B*1302-DRB1*0701 (6.19%), DRB1*0901-DQB1*0303 (14.27%), A*3001-B*1302-DRB1*0701 (5.36%), A*0207-Cw*0102-B*4601 (7.06%), A*3001-Cw*0602-B*1302-DRB1*0701 (5.36%), Cw*0602-B*1302-DRB1*0701-DQB1*0202 (6.12%) and A*3001-Cw*0602-B*1302-DRB1*0701-DQB1*0202 (5.29%). Presentation of the high-resolution alleles and haplotypes data at HLA-A, -B, -Cw, -DRB1 and -DQB1 loci will be useful for HLA matching in transplantation as well as for other medical and anthropological applications in the Chinese population.
