Figure 4. The two variants of HLA-DPB1*34:01 observed in this study.

Both DPB1 alleles share the same exon 2 sequence but have distinct exon 3 sequences, which link to different alleles of rs9277534. The SNPs distinguishing both exon 3 sequences are highlighted at their relative positions within the exon.
Variant 1 has meanwhile been entered into the IPD-IMGT/HLA database as DPB1*34:01. Variant 2 is in submission and will receive a different name.
