HLA-A29

HLA-A29 (A29) is a human leukocyte antigen serotype within HLA-A serotype group. The serotype is determined by the antibody recognition of α²⁹ subset of HLA-A α-chains. For A29, the alpha "A" chain are encoded by the HLA-A*29 allele group and the β-chain are encoded by B2M locus.^[1] This group currently is dominated by A*2902. A29 and A*29 are almost synonymous in meaning. A29 is a split antigen of the broad antigen serotype A19. A29 is a sister serotype of A30, A31, A32, A33, and A74.
