Identification of three new DRB1 alleles, DRB1*0107, *0425 and *13012 and confirmation of DRB4*01033.
The characterization of three novel DRB1 alleles is described, DRB1*0107, DRB1*0425 and DRB1*13012 as well as confirmation of DRB4*01033. Two alleles, DRB1*0107 and *0425, showed amino acid differences with previously identified HLA molecules. In DRB1*0107, the glutamine at position 10 was substituted by a glutamic acid. DRB1*0425 showed one amino acid difference with DRB1*0418 (I to F) at position 67, and five amino acid differences with DRB1*04011 at positions 67 (L to F), 70 (Q to D), 71 (K to R), 74 (A to L) and 86 (G to V). The alleles DRB1*13012 and DRB4*01033 had protein sequences identical to DRB1*13011 and DRB4*01031/01032, respectively. Nucleotide differences were present at position 306 for DRB1*13012 and at position 321 for DRB4*01033.
