PG - 497-502 LID - 10.1111/tan.12432 [doi] AB - We have characterized 372 novel human leukocyte antigen (HLA) class II alleles identified in newly registered stem cell donors, this includes 281 HLA-DRB1 alleles, 89 HLA-DQB1 alleles and 2 HLA-DPB1 alleles. Most novel alleles were single nucleotide variants when compared to their respective most homologous alleles. In 66.4% of all novel alleles non-synonymous nucleotide variations were identified, in 30.4% synonymous substitutions and in 3.2% nonsense mutations. Ninty-three (25.0%) novel alleles were found in several individuals; most often these were novel HLA-DRB1 alleles. Lastly, we underline the importance of recruiting ethnic minority donors in countries such as Germany and the United States, as novel alleles were frequently found among these groups.
