Abstract:
Human leukocyte antigen- (HLA-) A, HLA-B, HLA-C, HLA-DRB1, andHLA-DQB1allele and haplotype frequencies were studied in
a subset of 237 volunteer bone marrow donors registered at the South African Bone Marrow Registry (SABMR). Hapl-o-Mat software
was used to compute allele and haplotype frequencies from individuals typed at various resolutions, with some alleles in multiple allele
code (MAC) format. Four hundred and thirty-eight HLA-A, 235 HLA-B, 234 HLA-DRB1, 41 HLA-DQB1, and 29 HLA-C alleles are
reported. The most frequent alleles were A∗ 02:02g (0.096), B ∗ 07:02g (0.082), C∗ 07:02g (0.180), DQB1∗ 06:02 (0.157), and
DRB1 ∗ 15:01 (0.072). The most common haplotype was A∗ 03:01g~B ∗ 07:02g~C∗ 07:02g~DQB1∗ 06:02~DRB1∗ 15:01
(0.067), which has also been reported in other populations. Deviations from Hardy-Weinberg equilibrium were observed in A,
B, and DRB1 loci, with C~DQB1 being the only locus pair in linkage disequilibrium. This study describes allele and haplotype
frequencies from a subset of donors registered at SABMR, the only active bone marrow donor registry in Africa. Although the
sample size was small, our results form a key resource for future population studies, disease association studies, and donor
recruitment strategies.
