HLA‐A*33:25, a novel allele identified by sequence‐based typing, is a well‐documented allele in Koreans

The new allele, HLA-A*33:25, differs from A*33:03:01 by one nucleotide substitution in exon 4 (c.778G>A) which results in an amino acid change at codon 236 [GCAACA (Ala>Thr)] in β2-microglobulin-binding domain.
