Resistance to thyroid hormone is a syndrome involving reduced responsiveness of target tissues to thyroid hormone. Most cases involve mutations of the thyroid hormone receptor beta gene. Since many patients demonstrate tachycardia, goiter and elevated serum thyroid hormone levels, some patients have been misdiagnosed with Graves' disease, and nearly one third of patients are being treated inappropriately. It is important to keep this diagnosis in mind when a patient with elevated thyroid hormone level accompanied by normal or slightly increased TSH levels (SITSH) is encountered. Therapy with TRIAC has been used in several patients.
