WebCongenital hypothyroidism (CHT) is a condition resulting from an absent or under-developed thyroid gland (dysgenesis) or one that has developed but cannot make thyroid hormone because of a ‘production line’ problem (dyshormonogenesis). Babies with CHT cannot produce enough thyroid hormone for the body’s needs. WebThyroid dysgenesis: a cause of congenital hypothyroidism where the thyroid did not develop properly.
