Graves disease (GD) is an autoimmune thyroid disease and is associated with human leukocyte antigen (HLA)-DR3 and DQA1*0501 in Caucasians. However, the association of HLA with GD is less clear-cut in East Asian populations. We analyzed HLA-DRB1 and -DQB1 associations with GD in 198 Korean patients compared with 200 healthy controls. HLA-DRB1*0803 (27.8% vs. 14.5% in controls, OR = 2.27, corrected p [p(c)] = 0.03) and *1602 (5.1% vs. 0%, OR = 22.34, p(c) = 0.03) alleles and closely linked haplotypes, DRB1*0803-DQB1*0601 and DRB1*1602-DQB1*0502, conferred susceptibility to GD in Koreans. Weak association of DRB1*0301 with GD susceptibility was observed in male patients only (12.5% vs. 3.5%, OR = 3.57, p < 0.05). HLA-DRB1*0101, *0701, *1202, and *1302 alleles were weakly associated with resistance to the disease (OR < 0.5, p < 0.05). Some HLA alleles were weakly associated with clinical characteristics in GD patients. Patients with DRB1*1301-DQB1*0603 developed their diseases in younger ages and were more frequently associated with larger goiter (p < 0.05). Although HLA class II alleles associated with GD in Koreans were different from those in Caucasians, some associations are shared, such as association of DRB1*0301 in male patients and protective effect of DRB1*0701 to GD susceptibility.
