Oto-palato-digital syndrome type II.

We report a patient with a sporadic case of oto-palato-digital (OPD) syndrome type II. Parents and five previous sibs are normal. At 26 years of age the patient had conductive hearing impairment, cleft palate, a prominent forehead, a flat facies, and a broad nasal base resulting in the characteristic "pugilistic" appearance. Extension and supination were limited at the elbows; thumbs and halluces were broad. Many radiological abnormalities were noted: malformations of the cervical spine, pelvic abnormalities, bilateral coxa valga, genu valgum, small fibulae, pes equino varus, and 15 carpal bones. IQ improved dramatically from 65 to 95.
