Ankyloglossum superius syndrome.

The case of a male infant with the ankyloglossum superius syndrome is documented. In addition to oromandibular and limb malformations, the patient had extensive jejunal and ileal atresia. The cause of this syndrome remains unknown, but both genetic and intrauterine environmental factors have been suggested. There was no family history of other affected relatives, but throughout her pregnancy the mother had received imipramine, diazepam, chlorpromazine, and meclizine.
