HLA-A10

Human leukocyte antigen serotype


Summary

Human leukocyte antigen serotype

HLA-A10 is a broad antigen HLA-A serotype. The ancestral A10 type is believed to be A2601, which via gene conversion with other HLA-A alleles produced A2501, A3401, A4301 and A6601. A10 serotypes in general show a pattern of more recent expansion. A34 is an excellent example, appearing to have expanded from the middle east, with linkage disequilibrium with B alleles into Austronesia, South Pacific, Philippines and as far north as Taiwan (where it is found in the Taiwan Ami and Yami tribal groups but rare in ethnic Chinese nor in Hong Kong Chinese). A66 appears to have expanded from North Africa into the Middle East or Europe and A26 appears to have expanded Black Sea and, after the initial settlement from the southern West Pacific Rim peoples, into Japan . Whether this is a secondary migration from Africa or a re-expansion from within Eurasia is unclear.
