We have found one more association with a variant well known to be involved in autoimmune disease: R620W in PTPN22. This association was also seen in Denny et al. [4] (-value of , OR of 1.29) as well as in a small candidate gene study of Hashimoto thyroiditis [5] (OR of 1.77 (1.31–2.40) in a sample of 194 cases and 2064 controls). The gene discussed is PTPN22; the disease is autoimmune disease.
