Hallermann-Streiff Syndrome: A
rare inherited disorder characterized by dwarfism, craniofacial anomalies, a
“beak-like” nose, microcephaly that may appear brachycephalic, malar
hypoplasia, micrognathia, hypoplasia of the mandible, and cleft lip/palate.
The eye abnormalities may include strabismus, nystagmus, cataracts,
microphthalmia, and blue sclera. Affected individuals may show sparse hair
on the scalp and body (hypotrichosis), dental abnormalities, and skin
atrophy, especially on the nose and scalp. Most cases appear to be sporadic.
