A novel HLA-A allele, HLA-A*02:544.

The novel allele HLA-A*02:544 has two nucleotide changes from its most closely related allele, HLA-A*02:148. Firstly at nucleotide 255 where C → T (codon 60 GAC → GAT), resulting in a non-coding change as GAC and GAT both code for the same amino acid aspartic acid. Secondly at nucleotide 368 where T → G (codon 98 TTT → TGT) resulting in a coding change, 98 phenylalanine is changed to cysteine.
