Living with Intractable diarrhea-choanal atresia-eye anomalies syndrome

A rare syndrome in infants with hard-to-treat diarrhea, a blocked nasal passage, and eye differences.

Understanding Intractable diarrhea-choanal atresia-eye anomalies syndrome

Intractable diarrhea-choanal atresia-eye anomalies syndrome is a rare syndrome with hard-to-treat diarrhea in infancy and blocked back nasal passages (choanal atresia).

Other reported features include short stature, a prominent broad nasal bridge, a small jaw, a single crease across the palms, long-lasting inflammation of the cornea, low blood counts, and unusual hair texture. People do not have intellectual disability or immune deficiency, which helps tell it apart from other forms of infant diarrhea.
