Locus 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-DR8 (DR8) is a HLA
Human leukocyte antigen
The human leukocyte antigen system is the name of the major histocompatibility complex in humans. The super locus contains a large number of genes related to immune system function in humans. This group of genes resides on chromosome 6, and encodes cell-surface antigen-presenting proteins and...

The serological reaction of DR8 is relatively good. The serology of DRB1*0808, *0809 and *0813 to *0832 serotypes is unknown.
Disease associations
DQ8 is linked to papillary thyroid carcinomas , early onset pauciarticular juvenile chronic arthritis, primary biliary cirrhosisby allele
HLA-DRB1*0801 is linked to primary biliary cirrhosis In Mexicans DR8 is found more often in type-2 juvenile diabetes.HLA-DRB1*0803 is also linked to primary biliary cirrhosis

HLA-DR8 is not genetically linked to HLA-DR51 to DR53, but is linked to DQ4
HLA-DQ4
HLA-DQ4 is a serotype subgroup within HLA-DQ serotypes. The serotype is determined by the antibody recognition of β4 subset of DQ β-chains. The β-chain of DQ is encoded by HLA-DQB1 locus and DQ4 are encoded by the HLA-DQB1*04 allele group. This group currently contains 2 common alleles, DQB1*0401...
