Hallermann-Streiff syndrome is a rare, congenital condition characterized mainly by abnormalities of the skull and facial bones; characteristic facial features; sparse hair; eye abnormalities; dental defects; degenerative skin changes; and proportionate short stature.[1][2] Intellectual disability is present in some individuals.[2] Almost all reported cases of the condition appear to have occurred randomly for unknown reasons (sporadically) and are thought to have resulted from a new mutation in the affected individual.[3] Treatment is symptomatic and supportive.[4]
