The circulating levels of serum TSH and thyroid hormones represent biochemical phenotypes reflecting thyroid homeostasis. Studying the regulation of biochemical measures related to the thyroid in healthy individuals could prove essential in understanding the pathways that eventually lead to thyroid disease. It is the combined effect of genetic and environmental factors that give rise to these endophenotypes. It has been established that the measures reflecting thyroid homeosta...
