| Locus | chr.6 6p21.31 |  HLA-DR8 (DR8) is a HLA-DR serotype that recognizes the DRB1*0801 to *0807, and *0810 to *0812 gene products.  
  Serology
 DR8 serological recognition of the gene products of some DRB1*08 alleles[1]
| DRB1* | DR8 | Sample |  
| allele | % | size (N) |  
| 0801 | 95 | 1076 |  
| 0802 | 96 | 265 |  
| 0803 | 88 | 230[2] |  
| 0804 | 93 | 186 |  
| 0805 | >60 | 5 |  
| 0806 | >75 | 13 |  The serological reaction of DR8 is relatively good. The serology of DRB1*0808, *0809 and *0813 to *0832 serotypes is unknown.  
  Disease associationsDQ8 is linked to papillary thyroid carcinomas [3], early onset pauciarticular juvenile chronic arthritis[4][5], primary biliary cirrhosis[6]
  by alleleHLA-DRB1*0801 is linked to primary biliary cirrhosis[7] In Mexicans DR8 is found more often in type-2 juvenile diabetes.[8]
 HLA-DRB1*0803 is also linked to primary biliary cirrhosis[7]
