[Identification of a novel HLA allele A*29:49 using sequence based typing]

To report on a novel HLA-A allele, A*29:49, identified in a Chinese Han population by sequence based typing (SBT).

A donor from China Marrow Donor Programme (CMDP) was typed with a bi-allelic PCR-SBT kit, and no full matched result was obtained for the HLA-A locus. The novel HLA allele was verified with an allele-specific amplification SBT kit.

A novel HLA-A allele was identified, which has differed by one nucleotide from the closest matched allele, HLA-A*29:01:01:01, at position 368(A→T), codon 99 (TAT→TTT), resulting in an amino acid substitution (Y→F). Another allele was verified as A*02:06:01.

A novel HLA-A allele was identified and officially named as HLA-A*29:49 by the WHO Nomenclature Committee for Factors of the HLA System.
