HLA-A32 (A32) is a human leukocyte antigen serotype within HLA-A serotype group. The serotype is determined by the antibody recognition of α32 subset of HLA-A α-chains. For A32, the alpha "A" chain are encoded by the HLA-A*32 allele group and the β-chain are encoded by B2M locus.[1] This group currently is dominated by A*3201. A32 and A*32 are almost synonymous in meaning. A32 is a split antigen of the broad antigen serotype A19. A32 is a sister serotype of A29A30A31A33, and A74.

A32 Serotyping efficiency for the predominant allele is good. There are 16 known alleles that result in 15 isoforms of HLA-A32. One isoform may be poorly expressed.[3].
