HLA-A26 (A26) is an HLA-A serotype. The serotype identifies the more common HLA-A*26 gene products. A26 is a split antigen of the A10 broad antigen serotype group. A*2601 is believed to be the ancestral type for the A10 group, this group also includes A25, A34, A43 and A66.[1] A26 is broadly distributed but A26 is unusually common in Japan with a number of variants.

Serotype
Serotype recognition of most alleles is generally good.
