HLA-A24

HLA-A24 (A24) is a human leukocyte antigen serotype within HLA-A serotype group. The serotype is determined by the antibody recognition of α24 subset of HLA-A α-chains. For A24, the alpha, 'A', chain are encoded by the HLA-A*24 allele group and the β-chain are encoded by B2M locus. This group currently is dominated by A*2402. A24 and A*24 are almost synonymous in meaning.A24 is a split antigen of the broad antigen HLA-A9 and it is a sister serotype of HLA-A23.

A*2402 has one of the highest 'A' frequencies identified for a number of peoples, including Papua New Guineans, Indigenous Taiwanese (Eastern Tribals), Yupik and Greenland Eskimos. It is common over much of Southeastern Asia. In Eurasia it is least common in Ireland, and A24 is relatively uncommon in Africa except North Africa and Kenya.
