Thyroid hormone resistance (also resistance to thyroid hormone (RTH), and sometimes Refetoff syndrome) describes a rare syndrome in which the thyroid hormone levels are elevated but the thyroid stimulating hormone (TSH) level is not suppressed, or not completely suppressed as would be expected. The first report of the condition appeared in 1967.[1] Essentially this is decreased end organ responsiveness to thyroid hormones.[2] A new term "impaired sensitivity to thyroid hormone" has been suggested in March 2014 by Refetoff et al.[3]
