History

Pendred’s syndrome, hereditary metabolic condition that is characterized by deafness and defective incorporation of iodine into thyroid hormone, resulting in goitre or enlargement of the thyroid gland. Pendred’s syndrome is a major cause of congenital deafness. It does not produce symptoms of hypothyroidism (deficiency of thyroid activity) in most patients, nor does the condition affect life expectancy.
