HLA-A11 (A11) is a human leukocyte antigen serotype within HLA-A "A" serotype group. The serotype is determined by the antibody recognition of α11 subset of HLA-A α-chains. For A11, the alpha "A" chain are encoded by the HLA-A*11 allele group and the β-chain are encoded by B2M locus.[1] This group currently is dominated by A*1101. A11 and A*11 are almost synonymous in meaning. A11 is more common in East Asia than elsewhere, it is part of several long haplotypes that appear to have been frequent in the ancient peoples of Asia.[2]
