Disorders of thyroid gland

E00Congenital iodine-deficiency syndrome
Latin: Cretinismus endemicus congenitus
Includes:endemic conditions associated with environmental iodine deficiency either directly or as a consequence of maternal iodine deficiency. Some of the conditions have no current hypothyroidism but are the consequence of inadequate thyroid hormone secretion in the developing fetus. Environmental goitrogens may be associated.
