CCD is caused by changes (mutations) in the RUNX2 gene and inheritance is autosomal dominant. It may be inherited from an affected parent or occur due to a new mutation in the RUNX2 gene. Management may include dental procedures, treatment of sinus and ear infections, use of helmets for high-risk activities, and/or surgery for skeletal problems."

The diagnosis of pycnodysostosis is based on physical features and X-ray findings. Molecular genetic testing is available. Treatment should address the symptoms found in each patient and may include orthopedic monitoring, treatment of fractures, appropriate dental care, and craniofacial surgery."

At birth, the hands and feet may appear abnormally short and broad. Over time, the apparent disproportion becomes even more obvious, especially during the first years of life. Additional features may include: limited extension of the elbows and arms; progressive abnormal curvature of the spine; an enlarged head; and a slightly flattened midface. Acromesomelic dysplasia is inherited as an autosomal recessive trait. There are different types of acromesomelic dysplasia, which are distinguished by their genetic cause.
