Jones syndrome is a very rare condition characterized by gingival fibromatosis (enlargement and overgrowth of the gums) and progressive, sensorineural hearing loss. The onset of gingival fibromatosis usually occurs with the eruption of the permanent teeth. Excessive growth of the gums may cause displacement of teeth, over-retention of primary teeth, and increased spacing. Jones syndrome is inherited in an autosomal dominant manner, but the underlying genetic cause is not yet known. Only a few families with Jones syndrome have been reported.
