PG - 238-40 LID - 10.1111/j.1399-0039.2009.01296.x [doi] AB - Twenty-six novel human leukocyte antigen (HLA) class I alleles are described: 3 HLA-A alleles, 19 HLA-B alleles and 4 HLA-C alleles. Only one of the novel alleles (HLA-B*0753) was found in multiple individuals and likely is not uncommon in the population. Nineteen (approximately 70%) of the 26 novel alleles are single nucleotide substitution variants when compared with their most homologous allele. Four of these single nucleotide variants are silent substitutions, and one creates a null allele. The remaining novel alleles differ from their most similar allele by two to six nucleotide substitutions. Some of the new alleles encode novel codons and unique amino acid changes at polymorphic positions in the HLA-B lows (codons 30, 67 and 72), while HLA-Cw*0347 encodes an amino acid change at a position not previously reported to be polymorphic for this locus.
