Serology
Disease associations
DR8 is linked to papillary thyroid carcinomas,[3] early onset pauciarticular juvenile chronic arthritis,[4][5] primary biliary cirrhosis[6]
by allele
HLA-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]
