Intractable diarrhea-choanal atresia-eye anomalies syndrome is characterized by the association of intractable diarrhea of infancy with choanal atresia. Short stature, a prominent and broad nasal bridge, micrognathia, single palmar creases, chronic corneal inflammation, cytopenia, and abnormal hair texture were also reported. So far, the syndrome has been described in three children from the same family. The absence of intellectual deficit and immune deficiency allow this syndrome to be distinguished from other forms of intractable diarrhea of infancy described previously.

A rare multiple congenital anomaly syndrome characterized by bilateral choanal atresia associated with characteristic cranio-facial dysmorphism (hypertelorism with narrow palpebral fissures, coloboma of inferior eyelid with presence of eyelashes medial to the defect, prominent nasal bridge, thin lips, prominent ears), that can be accompanied by hearing loss, unilateral cleft lip, preauricular tags, cardiac septal defects and anomalies of the kidneys. Affected individuals have normal intelligence.	Finding site	False	Structure of choana (body structure)	Inferred relationship	Some	4
