Mondo Description X-linked cleft palate and ankyloglossia is a rare, genetic developmental defect during embryogenesis syndrome characterized by the association of complete, partial or submucous cleft palate and ankyloglossia. Patients may also present abnormal uvula (e.g. absent, bifid, shortened or laterally deviated), short lingual frenulum and dental anomalies (e.g. buccal crossbite, absent and/or misshapen teeth). Digital abnormalities, such as mild clinodactyly and/or syndactyly, have also been reported.

Uniprot Description A congenital mouth abnormality characterized by fissure of the soft and/or hard palate, due to faulty fusion. Some patients also manifest ankyloglossia, a condition in which movements of the tongue are restricted. Complete ankyloglossia is due to fusion between the tongue and the floor of the mouth. Partial ankyloglossia is due to a short lingual frenum or one which is attached too near the tip of the tongue.
