Researchers discover new genetic mutation for congenital thyroid condition

​One in every 2,000 newborns has a lack or diminished thyroid hormone at birth, which can cause irreparable mental and development damage if left untreated. Thyroid stimulating hormone (TSH), produced by the pituitary gland, regulates the production of thyroid hormone. When thyroid hormone levels fall, TSH levels rise. As a result, TSH is commonly used to screen babies for thyroid hormone insufficiency, allowing for early treatment and prevention of the devastating effects.
