title: Novel alleles at the HLA-DRB1 and -DQB1 loci.
abstract: Twelve novel human leukocyte antigen class II alleles are described; eight DRB1 alleles and four DQB1 alleles. Nine of the variants are single nucleotide substitutions from their most homologous allele, of which six result in amino acid changes (DRB1*0459, *1156 and *1522; DQB1*0205, *0320 and *0321) and three are silent substitutions (DRB1*030105 and *040304, and DQB1*030104). The remaining alleles (DRB1*0906, *1464 and *1468) differ from their most similar alleles by two to three nucleotide substitutions which alter one to two amino acids.
