Abstract excerpt
Thyroid hormone action is mediated through its nuclear receptors (TRs), which bind to target DNA sequences [thyroid hormone response element (TRE)] as a homodimer or a heterodimer with 9-cis-retinoic acid receptors. Mutations of TR beta identified in patients with resistance to thyroid hormone (RTH) cluster primarily at two areas separated by the putative dimerization region. Two TR beta mutations were newly...
