• Two families each had two siblings with hypothyroidism due to ectopy and hypoplasia of the thyroid. A genetic factor controlling normal thyroid development and descent may be responsible, and the importance of plasma thyroid-stimulating hormone estimation in borderline hypothyroid cases is emphasized. We suggest screening of siblings of patients with ectopic thyroid for hypothyroidism.
