Cleidocranial Dysplasia
Background
Cleidocranial Dysplasia: CCD; Cleidocranial Dysostosis
Cleidocranial dysplasia (CCD) is a hereditary congenital (meaning it is present at birth) skeletal condition characterised by delayed closure of the cranial vault sutures, (the seams between the bones which make up the cranial vault (skull)), hypoplastic (under developed) or aplastic (absent) clavicles (collar bones) and multiple dental anomalies. It was described independently by SchItuthauer (1871) and Marie and Sainton (1897).
