Description

Approximately 10% of patients with congenital hypothyroidism harbor inborn errors of metabolism in one of the steps for thyroid hormone synthesis in thyrocytes (Vono-Toniolo et al., 2005). The most prevalent cause of thyroid dyshormonogenesis is TPO deficiency (Park and Chatterjee, 2005). Defects in TPO cause a severe form of congenital hypothyroidism characterized by a complete and immediate release of accumulated radioiodide from the thyroid after sodium perchlorate administration (Bakker et al., 2000). This release of radioiodide represents total iodine organification defect (TIOD), a disruption of the process by which iodide present in the thyroid is oxidized by hydrogen peroxide and bound to tyrosine residues in thyroglobulin (TG ) to form iodotyrosine.
