- HLA-A10
HLA-A10 is a broad antigen HLA-A serotype. The ancestral A10 type is believed to be A*2601, which via
gene conversion with otherHLA-A allele s produced A*2501, A*3401, A*4301 and A*6601.cite journal | author = Madrigal JA, Hildebrand WH, Belich MP, "et al" | title = Structural diversity in the HLA-A10 family of alleles: correlations with serology | journal = Tissue Antigens | volume = 41 | issue = 2 | pages = 72–80 | year = 1993 | pmid = 8475492 | doi = ] 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 Austronesiacite journal | author = Bugawan TL, Mack SJ, Stoneking M, Saha M, Beck HP, Erlich HA | title = HLA class I allele distributions in six Pacific/Asian populations: evidence of selection at the HLA-A locus | journal = Tissue Antigens | volume = 53 | issue = 4 Pt 1 | pages = 311–9 | year = 1999 | pmid = 10323335 | doi = ] , South Pacificcite journal | author = Maitland K, Bunce M, Harding RM, "et al" | title = HLA class-I and class-II allele frequencies and two-locus haplotypes in Melanesians of Vanuatu and New Caledonia | journal = Tissue Antigens | volume = 64 | issue = 6 | pages = 678–86 | year = 2004 | pmid = 15546341 | doi = 10.1111/j.1399-0039.2004.00328.x] , Philippinescite journal | author = Bugawan TL, Klitz W, Alejandrino M, "et al" | title = The association of specific HLA class I and II alleles with type 1 diabetes among Filipinos | journal = Tissue Antigens | volume = 59 | issue = 6 | pages = 452–69 | year = 2002 | pmid = 12445315 | doi = ] 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). A*66 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.References
