Abstract:
:The distributions of HLA allele and haplotype are variable in different ethnic populations and the data for some populations have been published. However, the data on HLA-C and HLA-DQB1 loci and the haplotype of HLA-A, HLA-B, HLA-C, HLA-DRB1 and HLA-DQB1 loci at a high-resolution level are limited in Zhejiang Han population, China. In this study, the frequencies of the HLA-A, HLA-B, HLA-C, HLA-DRB1 and HLA-DQB1 loci and haplotypes were analysed among 3,548 volunteers from the Zhejiang Han population using polymerase chain reaction sequencing-based typing method. Totals of 51 HLA-A, 97 HLA-B, 45 HLA-C, 53 HLA-DRB1 and 27 HLA-DQB1 alleles were observed. The top three frequent alleles of HLA-A, HLA-B, HLA-C, HLA-DRB1 and HLA-DQB1 loci were A*11:01 (23.83%), A*24:02 (17.16%), A*02:01 (11.36%); B*40:01 (14.08%), B*46:01 (12.20%), B*58:01 (8.50%); C*07:02 (18.25%), C*01:02:01G (18.15%), C*03:04 (9.88%); DRB1*09:01 (17.52%), DRB1*12:02 (10.57%), DRB1*15:01 (9.70%); DQB1*03:01 (22.63%), DQB1*03:03 (18.26%) and DQB1*06:01 (10.88%), respectively. A total of 141 HLA-A-C-B-DRB1-DQB1 haplotypes with a frequency of ≥0.1% were found and the haplotypes with frequency greater than 3% were A*02:07-C*01:02:01G-B*46:01-DRB1*09:01-DQB1*03:03 (4.20%), A*33:03-C*03:02-B*58:01-DRB1*03:01-DQB1*02:01 (4.15%), A*30:01-C*06:02-B*13:02-DRB1*07:01-DQB1*02:02 (3.20%). The likelihood ratios test for the linkage disequilibrium of two loci haplotypes was revealed that the majority of the pairwise associations were statistically significant. The data presented in this study will be useful for searching unrelated HLA-matched donor, planning donor registry and for anthropology studies in China.
