One of the common causes of this is autoantibodies produced by the thyroid-stimulating hormone (TSH) receptor and the components of the thyroid hormone (TH) synthesis system in thyrocytes, which leads to autoimmune diseases, such as autoimmune hyperthyroidism (Graves’ disease) and autoimmune thyroiditis (Hashimoto’s disease) [3,4]. This evidence concerns the gene TH and Graves disease.
