Locus (genetics)
In the fields of genetics and genetic computation, a locus is the specific location of a gene or DNA sequence on a chromosome. A variant of the DNA sequence at a given locus is called an allele. The ordered list of loci known for a particular genome is called a genetic map...

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. and the DRB4 locus presence is linked to HLA-DR7
HLA-DR7
HLA-DR7 is a HLA-DR serotype that recognizes the DRB1*0701 to *0705 gene products.-Serology:The serological reaction of DR7 is excellent for *0701. The serology of *0703 to *0705 to *0709, and *0711 to *0714 serotypes is unknown. DRB1*0710N is a null allele. DRB1*0702 nomenclature has been...

 seropositivity. The DRB4*locus was apparently duplicated from an ancestor of the DRB1-DRB4 common locus around 5 million years ago.

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. and lowered because of both transcriptional and post-transcriptional regulation.

Primary biliary cirrhosis, often abbreviated PBC, is an autoimmune disease of the liver marked by the slow progressive destruction of the small bile ducts within the liver. When these ducts are damaged, bile builds up in the liver and over time damages the tissue. This can lead to scarring,...
