Thyroid hormone resistance (THR), also known as resistance to thyroid hormone (RTH), is an inherited condition characterized by reduced end-organ responsiveness to thyroid hormone, caused by mutations in the thyroid hormone receptor gene. Patients typically present with elevated thyroid hormone levels (T3 and T4) with normal, or slightly elevated thyroid-stimulating hormone (TSH) levels.1 In a majority of cases, the disease is caused by a mutation in the thyroid receptor beta (TR-beta) gene. Patients can present with signs and symptoms of hypothyroidism or hyperthyroidism or can be asymptomatic. We present a case of a 16-year-old male who was referred for endocrinologic evaluation after abnormal findings in the thyroid function panel.
