Two new HLA DPB1 alleles identified by sequence-based typing: DPB1*8201 and DPB1*8301.

Two new HLA DPB1 alleles were identified by sequence-based typing and are reported. Both alleles differ from DPB1*0402 by a single nucleotide: DPB1*8201 has a difference at position 359 (codon 91) leading to an amino acid change from arg to his, making this position a new polymorphic site; DPB1*8301 has a difference at position 280 (codon 65) changing the amino acid from ile to phe.
