Cleidocranial Dysplasia
Cleidocranial Dysplasia is a genetic disorder that affects the bone development in the body. It is caused by mutations in the RUNX2 gene. The disorder can cause several skeletal abnormalities, including underdeveloped or absent collarbones, delayed eruption or absence of permanent teeth, and abnormal skull shape. People with Cleidocranial Dysplasia may also have short stature and other skeletal abnormalities, such as curvature of the spine. The disorder can be diagnosed through genetic testing and a physical examination. Treatment may include dental and orthopedic interventions, such as braces and surgery. The prognosis for people with Cleidocranial Dysplasia varies depending on the severity of the disorder and the extent of the skeletal abnormalities. However, most people with the disorder can live normal lives with appropriate care and management.
Symptoms of Cleidocranial Dysplasia
What are the most common symptoms of Cleidocranial Dysplasia?
The most common symptoms of Cleidocranial Dysplasia include delayed closure of the soft spot on the skull, abnormal or absent collarbones, short stature, dental abnormalities, and frequent ear infections. Patients may also experience a midface hypoplasia which can cause problems with breathing and sinus congestion.
How does a person inherit Cleidocranial Dysplasia?
Cleidocranial Dysplasia is inherited in an autosomal dominant pattern, meaning that a person only needs to inherit one copy of the mutated gene from one parent to develop the condition. However, up to half of all cases occur due to new mutations.
What is the main genetic mutation associated with Cleidocranial Dysplasia?
The main genetic mutation associated with Cleidocranial Dysplasia is a mutation in the RUNX2 gene, which provides instructions for making a protein that is essential for the development and maintenance of bones.
Can Cleidocranial Dysplasia cause dental abnormalities?
Yes, Cleidocranial Dysplasia is often associated with dental abnormalities, including delayed tooth eruption, supernumerary teeth, and teeth that are misaligned or have abnormal roots. Patients may also have a high-arched palate, crowded teeth, and a small lower jaw.
How does Cleidocranial Dysplasia affect bone development?
Cleidocranial Dysplasia affects bone development by disrupting the normal process of bone formation and maintenance. The mutant protein produced by the RUNX2 gene leads to the underdevelopment of certain bones, particularly those of the skull and collarbones. The condition also affects the development of teeth, leading to the dental abnormalities that are commonly seen in affected individuals.
Diagnosis of Cleidocranial Dysplasia
What imaging tests can be used to diagnose cleidocranial dysplasia?
Various imaging tests can be used to diagnose cleidocranial dysplasia, including X-rays and CT scans. X-rays can be used to identify abnormal growth of bones, particularly within the skull and chest, while CT scans can show more detailed images of the bone structure, including the extent of any abnormalities.

Physical characteristics that may be used in the clinical diagnosis of cleidocranial dysplasia include abnormalities in bone growth, particularly within the skull and chest. Affected individuals may also have shorter stature, a narrow and elongated face, and delayed closure of the fontanelles, or the soft spots on an infant`s skull.
Treatments of Cleidocranial Dysplasia
What are the common surgical interventions used in the management of Cleidocranial Dysplasia?
Common surgical interventions used in the management of Cleidocranial Dysplasia include cranial reshaping surgery, operations to correct dental abnormalities such as tooth impaction and malocclusions, and removal of supernumerary teeth. Surgery to correct shoulder abnormalities, such as acromioclavicular joint reconstruction, may also be necessary. In severe cases, spinal surgeries may be required to correct spinal abnormalities.
How is orthodontic treatment used to manage Cleidocranial Dysplasia?
Orthodontic treatment is often used to manage Cleidocranial Dysplasia. This may include braces, headgear, and other corrective devices to align teeth and manipulate jaw growth. In some cases, orthognathic surgery may be necessary to correct severe jaw alignment abnormalities.
What non-surgical interventions are used to manage complications of Cleidocranial Dysplasia?
Non-surgical interventions used to manage complications of Cleidocranial Dysplasia may include hearing aids, speech therapy, and physical therapy to improve mobility and strength. Genetic counseling and psychological support may also be necessary to address the emotional impact of the condition.
Can medication be used to manage the symptoms of Cleidocranial Dysplasia?
Medication is not typically used to manage the symptoms of Cleidocranial Dysplasia. However, pain relief medication may be prescribed following surgical procedures or to manage chronic pain associated with the condition.
How is physical therapy utilized for the management of Cleidocranial Dysplasia?
Physical therapy can be utilized to manage Cleidocranial Dysplasia by improving overall mobility, coordination, and strength. This may include exercises to enhance pelvic stability, improve gait, and reduce the risk of falls. A physical therapist can also help coordinate care with other healthcare providers and provide resources for home exercise programs.
Prognosis of Cleidocranial Dysplasia
What is the typical life expectancy for someone with Cleidocranial Dysplasia?
The typical life expectancy for someone with Cleidocranial Dysplasia is not significantly different from that of the general population. This condition primarily affects bone development and is not associated with an increased risk of mortality.
How does the severity of Cleidocranial Dysplasia impact long-term prognosis?
The severity of Cleidocranial Dysplasia can impact long-term prognosis, depending on the extent to which it affects skeletal development and function. More severe cases may lead to greater functional impairments and a higher likelihood of complications, which can negatively impact overall health and well-being.
