Synonyms: Gonzales-del Angel syndrome

Delayed membranous cranial ossification is a rare genetic primary bone dysplasia characterized by absent ossification of calvarial bones at birth and characteristic facial dysmorphisms (frontal bossing hypertelorism downward-slanting palpebral fissures proptosis flat nasal bridge low-set ears midface retrusion). Patients present a soft skull at birth which over time progressively ossifies and in adulthood typically results in a deformed skull (with brachycephaly and prominent occiput). No other skeletal abnormalities are associated and patients have normal cognitive and motor development.
