High-resolution HLA-A, HLA-B, and HLA-DRB1 haplotype frequencies from the French Bone Marrow Donor Registry


We have estimated human leukocyte antigen (HLA) haplotype frequencies using the maximum likelihood mode, which accommodates typing ambiguities. The results of the frequency distribution of the 7015 haplotypes obtained are presented here. These include a total of 114 HLA-A, 185 HLA-B, and 76 HLA-DRB1 unique alleles at each locus. Across all populations, although the most common individual HLA alleles were HLA-A*02:01 (29.0%), HLA-B*07:02 (11.4%), and HLA-DRB1*07:01 (15.9%), the most frequent haplotype was found to be HLA-A*01:01~B*08:01~DRB1*03:01.
