PG - 607-9 LID - S0198-8859(13)00037-2 [pii] LID - 10.1016/j.humimm.2013.01.026 [doi] AB - Contribution of the human leukocyte antigen (HLA) subtype to Hashimoto's thyroiditis (HT) that requires replacement therapy with levothyroxine remains unclear in the Japanese population. The frequencies of HLA DR-DQ haplotypes were compared between patients with HT requiring levothyroxine replacement therapy and the control individuals. We studied 82 patients with HT requiring levothyroxine replacement therapy. The frequencies of DRB1*08:03-DQB1*06:01 and DRB1*09:01-DQB1*03:03 haplotypes were significantly higher in HT patients, whereas those of DRB1*13:02-DQB1*06:04 and DRB1*15:01-DQB1*06:02 haplotypes were significantly lower in these patients than in the controls. Deduced from known linkage disequilibria, DRB1*13:02-DQB1*06:04 and DRB1*15:01-DQB1*06:02 haplotypes share the same DQA1*01:02 allele. Since DQB1*06:02 and DQB1*06:04 molecules differ in the beta chain by 7 residues, these DQB1 genes are very similar. The DQA1*01:02-DQB1*06 (DQB1*06:02 or DQB1*06:04) haplotype might play a pivotal role in the resistance to HT. CI - Copyright (c) 2013 American Society for Histocompatibility and Immunogenetics.
