title: [The linkage of the major histocompatibility complex to autoimmune thyroid diseases].
abstract: To investigate the association between human leukocyte antigen (HLA) and development of autoimmune thyroid diseases such as Graves' disease (GD), Hashimoto's thyroiditis (HT), and Graves' disease patients with undetectable TSH-binding inhibitor immunoglobulin (TBII-negative GD), HLA typing was done. 1. We previously reported increased frequencies of HLA-A2 and DPB1*0501 in TBII-positive GD patients, 2. significantly increased frequencies of HLA-A2 and DPB4*0101 in patients with HT, 3. more TBII-negative GD patients having both HLA-B46 and DPB1*0202 than those having each allele alone, suggesting that these 2 alleles may play a synergistic role in controlling the susceptibility to TBII-negative GD, and 4. contrarily that the frequencies of DQA1*0102 in HT patients and of DQB1*0501 in GD patients were significantly decreased, suggesting that DQA1*0102 and DQB1*0501 might confer resistance to the development of HT and GD.
