Locus chr.6 6p21.31

HLA-DR53 is an HLA-DR serotype that recognizes gene products of HLA-DRB4 locus. There are 13 alleles at this locus that encode 7 proteins.

DRB3, DRB4, and DRB5 are minor DR beta encoding loci, they have been recognized as having distinct evolution.[1] and the DRB4 locus presence is linked to HLA-DR7 seropositivity. The DRB4*locus was apparently duplicated from an ancestor of the DRB1-DRB4 common locus around 5 million years ago.[2]

DRB4 locus is only apparent in a small subset of DQ haplotypes, and most individuals lack DRB4. In addition the level of normal expression is 8 fold lower than the DRB1 in cells which can express both.[3] and lowered because of both transcriptional and post-transcriptional regulation[4].
