   Hypothyroidism is the most common thyroid disorder, affecting about 5% of the general population. Here we present the first large genome-wide association study of hypothyroidism, in 2,564 cases and 24,448 controls from the customer base of 23andMe, Inc., a personal genetics company. We identify four genome-wide significant regions, two of which are well known to be involved with a large spectrum of autoimmune diseases: rs6679677 near PTPN22 and rs3184504 in SH2B3 (p-values 3.5E-13 and 3.0E-11, respectively). We also report associations with rs4915077 near VAV3 (p-value 8.3E-11), another gene involved in immune function, and rs965513 near FOXE1 (p-value 3.1E-14). Of these, the association with PTPN22 confirms a recent small candidate gene study, and FOXE1 was previously known to be associated with thyroid-stimulating hormone (TSH) levels. Although SH2B3 has been previously linked with a number of autoimmune diseases, this is the first report of its association with thyroid disease. The VAV3 association is novel.
