What it is

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.

ICD-10 codes

Q38.6filed under a broader ICD-10 category — shared with 1 other rare disease

ICD-10 has no distinct code for most rare diseases, so many are filed under the nearest available one. A shared code identifies the group, not this disease — the ORPHAcode above is what identifies it.
