evaluated thyroid function and the levels of anti-Tg Abs and antithyroid peroxidase autoantibodies (anti-TPO Abs) in patients with sarcoidosis compared to patients with chronic obstructive pulmonary disease; they found that in patients with sarcoidosis anti-Tg Abs were significantly increased, while anti-TPO Abs were within the normal range. This evidence concerns the gene TG and sarcoidosis.
