Cleidocranial Dysplasia (CCD)
Other names: CLCD; Cleidocranial dysostosis; Dysplasia cleidocranial; Marie-Sainton disease.
What is CCD?
Cleidocranial Dysplasia (CCD) is a rare genetic condition that affects the development of bones and teeth. Individuals with CCD may have underdeveloped bones of the skull, resulting in a distinctive appearance characterized by a prominent forehead and a broad, flat skull. The fontanels (spaces between the bones of an infant’s skull where the bones have not yet fused together) may remain open longer than usual in affected individuals. CCD can also affect the development of teeth, resulting in delayed or incomplete eruption of teeth. When teeth appear, they may also be misshapen, crowded, or not properly aligned. Individuals with CCD may also have underdeveloped or missing collarbones, short stature, abnormal curvature of the spine, osteopenia or osteoporosis, and joints that are hypermobile or which may dislocate easily.
Causes/Genetics
CCD is caused by mutations in the RUNX2 gene, which plays an important role in the development of bones and teeth. CCD is inherited in an autosomal dominant pattern, which means that an individual only needs to inherit one copy of the mutated gene from either parent to develop the condition.
Treatment
Treatment may include a combination of orthodontic and surgical interventions to correct the dental and skeletal anomalies. Early diagnosis and intervention can improve the overall quality of life for individuals with CCD. Genetic counseling may also be recommended for individuals and families affected by CCD.
