title: Identification of two novel HLA-B alleles in the Brazilian population: B*4509 and B*5212.
abstract: Human leucocyte antigen (HLA)-B*4509 differs from the closest HLA-B*4502 by three nucleotides that lead to changes of Tyr113His, Asn114Asp and Phe116Ser. HLA-B*5212 differs from HLA-B*520101 by a single nucleotide substitution, leading to a change of Asn114Asp.
