title: A new HLA-DR4 allele, DRB1*0474, with an unusual residue at position 77.
abstract: We report here a new DR4 allele, DRB1*0474, identified in a volunteer hematopoietic stem cell donor of the Swiss National Registry. DRB1*0474 differs from DRB1*040701 by two nucleotide residues resulting in a single Thr --> Asn substitution at codon 77.
