Familial goiter due to defective iodide organification has been divided into three genetic types. Type A, with cretinism, lacks peroxidase activity completely. Type C, with euthyroidism, apparently reflects a defect in the association of the hematin prosthetic group with the peroxide apoenzyme. Type B is Pendred's syndrome, with euthyroidism and nerve deafness, but no specific enzyme defect is known.
Our patient, a 12-year-old girl, had a goiter, nerve deafness, and a positive Perchlorate discharge, as did both of her parents and all five siblings. The void volume from Sephadex G-200 chromatography of a 105 000 g supernatant contained 88% of
