Our results suggest that these variants have pleiotropic effects, although they tend to affect TSH through actions in the thyroid gland....
Since the thyroid gland is controlled by the pituitary gland and hypothalamus, disorders of these tissues can also affect thyroid function and cause thyroid problems.
