- Abstract
- Background Recently, the association of a common STAT4 haplotype with type 1 diabetes (T1D) as well as rheumatoid arthritis has been documented in Caucasians and Koreans. STAT4 is involved in the signalling of interleukin-12 and gamma IFN, as well as interleukin-23. To discover genes affecting the susceptibility of common autoimmune diseases, we studied the association of polymorphisms in STAT4 with autoimmune thyroid disease (AITD) as well as T1D in the Korean population.Subjects and methods Four single-nucleotide polymorphisms on the chromosome 2q (rs11889341, rs7574865, rs8179673, and rs10181656), which were found to associate with rheumatoid arthritis were examined for association in a Korean sample of 428 AITD, 418 T1D patients, and 1060 controls.Results The minor alleles of all four single-nucleotide polymorphisms and the reconstructed STAT4 haplotypes conferred significant degree of risk for AITD (p = 10(-2) to 10(-4)). Although we found a weak association of rs11889341 with T1D (p < 0.05), the same haplotypes were not associated with T1D susceptibility. When we stratified T1D patients according to the age of onset, the minor alleles of all four single-nucleotide polymorphisms and the same haplotypes showed significant association with the susceptibility of T1D in the early-onset subgroup (p < 0.01), not in the late-onset subgroup.Conclusion STAT4 alleles and the same haplotypes might influence cytokine signalling, and therefore the development of AITD as well as T1D. These results reinforce the influence of STAT4 gene as a general autoimmune gene. Copyright (C) 2011 John Wiley & Sons, Ltd.
