Definition

Cleidocranial dysplasia (CCD), also known as cleidocranial dysostosis, is a hereditary condition characterized by abnormal clavicles, delayed fusion of the bones in the skull, extra teeth, short stature, and other skeletal changes.

Description

Cleidocranial dysplasia is one of the skeletal dysplasia conditions, a large family of disorders involving abnormal growth and development of the skeleton.

CCD involves a characteristic group of abnormalities affecting primarily the skull, teeth, and clavicles. Other bones, such as the ribs, pelvis, and bones of the hands and feet may also be affected. Older children and adults with CCD are typically shorter than average. Most individuals with this condition do not have significant physical or mental disability.
