General Discussion

Lacrimo-auriculo-dento-digital (LADD) syndrome is an extremely rare genetic disorder characterized by abnormalities affecting the lacrimal and salivary glands and ducts, ears, teeth and fingers and toes. The most common findings involve malformations in the network of structures of the eye that secrete tears and drain them from the eyes (lacrimal apparatus) and abnormalities of the forearms and fingers. Specific symptoms may vary greatly from case to case. LADD syndrome may occur sporadically or be inherited as an autosomal dominant trait.
