title: Expanding diversity at the HLA-B locus: 28 novel HLA-B alleles.
abstract: Twenty-eight novel human leukocyte antigen-B alleles are described: one B*07 (*0745), two B*08 (*0826 and *0831), one B*27 (*2731), four B*35 (*350106, *350402, *3566, and *3568), two B*37 (*370102 and *3711), two B*38 (*380102 and *3813), two B*39 (*3935 and *3939), one B*41 (*4108), one B*42 (*4209), two B*44 (*4444 and *4448), two B*48 (*480302 and *4815), one B*51 (*5140), one B*55 (*5523), one B*56 (*5617), two B*57 (*570103 and *5710), and three B*15 (*9505, *9510, and *9519). Sixteen of the variants are single-nucleotide substitutions from their most homologous allele, of which 10 result in amino acid changes (B*0745, *0831, *3813, *3935, *3939, *4815, *9505, *9509, *9510, and *9519) and 6 are silent substitutions. The remaining alleles (B*0826, *2731, *3566, *3568, *3711, *4108, *4209, *4444, *4448, *5140, *5523, *5617, and *5710) differ from their most similar alleles by two to seven nucleotides substitutions, altering from one to five amino acids.
