People with cleidocranial dysostosis have a forehead and jaw are prominent and the area of half of the nose (nasal bridge) is wide.
The bones of the clavicle may be absent or have an abnormal development. This makes the shoulders together in front of body.
The primary teeth do not fall off at the expected time. The permanent teeth may develop later than normal and an additional series of these teeth grows inward. This causes the normal teeth are crooked.
The disease does not affect the intelligence of the patient.
Other symptoms may include:
Ability to gather both shoulders in front of body
Delay in the closure of the fontanelles ("soft spots")
Joints loose
Prominent forehead (bossing front)
Forearms shorts
Fingers of the hand short
Cleidocranial dysplasia (CHD) is a rare genetic disorder of bone growth characterized by clavicles hipoplásicas or aplásicas, persistence of fontanelles and sutures open, and multiple dental abnormalities.
