Introduction: Resistance to thyroid hormone (RTH) is an inherited syndrome characterized by reduced responsiveness of target tissues to thyroid hormone (TH). It is characterized by high serum concentrations of free T4 (Ft4) and usually free T3 (Ft3) accompanied by normal or slightly high serum TSH concentrations. When RTH is suspected, the diagnosis should be confirmed by direct sequencing of the TR-β gene to identify mutations....

Resistance to thyroid hormone (RTH) is a genetic disease characterized by a reduced target tissue responsiveness to thyroid hormones and increased or normal TSH level despite elevated levels of thyroid hormones. This condition is mainly caused by mutations of thyroid hormone receptor beta (THRB) gene. The role of THRB mutation in carcinogenesis is still unclear. In here, we report a case of papillary thyroid carcinoma (PTC) with RTH, with a past medical history of subtotal thy...
