PG - 195-202 LID - 10.1111/j.1399-0039.2011.01704.x [doi] AB - Ninety-six novel human leukocyte antigen (HLA) class I and class II alleles are described from volunteers for the 'Be The Match Registry(R)': 15 HLA-A alleles, 11 HLA-C alleles, 36 HLA-B alleles and 34 HLA-DRB1 alleles. Sixty-eight ( approximately 71%) of the 96 novel alleles are single nucleotide substitution variants when compared with their most homologous allele. Twenty-three of these single nucleotide variants are silent substitutions and one creates a non-expressed allele (B(*) 27:59N). The remaining novel alleles differ from their most similar allele by two to five nucleotide substitutions. One of the novel HLA-A alleles (A(*) 11:52Q) is of questionable expression because of a deletion of codon 11. Three of the novel alleles encode amino acid changes at codons 63 (HLA-C), 88 (HLA-B) and 79 (HLA-DRB1) which have not previously been reported to be polymorphic in these loci. Some of the new alleles encode novel codons and unique amino acid changes at polymorphic positions in the HLA-A (codons 115, 149 and 168), HLA-C (codon 90), HLA-B (codons 23, 44, 70, 120 and 153) and HLA-DRB1 (codon 88) loci.
