Additional Information:

Description: (OMIM) Hallermann-Streiff syndrome is characterized by a typical skull shape (brachycephaly with frontal bossing), hypotrichosis, microphthalmia, cataracts, beaked nose, micrognathia, skin atrophy, dental anomalies, and proportionate short stature (Hallermann, 1948; Streiff, 1950; Francois, 1958). Mental retardation is present in ...
Clinical Description OMIM Hallermann (1948) and Streiff (1950) reported patients with dyscephaly, a 'bird-like' face, congenital cataracts, and microphthalmia. Francois (1958) identified similar reported cases with the additional features of hypotrichosis, skin atrophy, dental anomalies, and short stature.
