Locus chr.6 6p21.31

HLA-DR51 is a HLA-DR serotype that recognizes the antigens encoded by the minor DR locus HLA-DRB5.

DRB3, DRB4, and DRB5 are minor DR beta encoding loci, they have been recognized as having distinct evolution,[1] having diverged from DRB1 approximately 4 million years ago.[2]

DRB5 locus is only apparent in a small subset of DR haplotypes, and most individuals lack DRB5.
