Cleidocranial dysplasia is a rare genetic disorder characterized by abnormal development of the bones and teeth. It affects both males and females, with the frequency of occurrence estimated to be between 1 in 100,000 and 1 in 1,000,000 individuals worldwide. The condition is also known by other names such as cleidocranial dysostosis and cleidocranial dysostosis syndrome.

The main features of cleidocranial dysplasia include abnormalities of the bones and teeth. People with this condition may have open fontanelles (soft spots) in the skull, delayed closure of the cranial sutures, and underdeveloped or absent collarbones. Dental abnormalities often include delayed eruption of permanent teeth, overcrowding, and misalignment. Additionally, individuals with cleidocranial dysplasia may have other skeletal abnormalities such as short stature and abnormalities of the hip and spine.

The genetic cause of cleidocranial dysplasia is mutations in the RUNX2 gene. This gene plays a critical role in the development and maintenance of bones and teeth. Mutations in the RUNX2 gene can disrupt the normal function of bone cells and impair bone formation, leading to the characteristic features of cleidocranial dysplasia. Inheritance is autosomal dominant, meaning that a person with a mutation in one copy of the RUNX2 gene has a 50% chance of passing the mutation on to each of their children.

Diagnosis of cleidocranial dysplasia can be made based on clinical features, dental examination, and genetic testing. X-rays and other imaging studies may also be used to evaluate the extent of skeletal abnormalities. Genetic testing can confirm the presence of mutations in the RUNX2 gene.

There is currently no cure for cleidocranial dysplasia, but treatment is focused on managing the symptoms and complications associated with the condition. This may include dental interventions such as tooth extraction and orthodontic treatment, as well as surgical intervention for skeletal abnormalities. Regular follow-up and monitoring is important to address any potential issues and provide appropriate support and resources for patients and their families.

Research and scientific studies on cleidocranial dysplasia are ongoing to further understand the genetic causes and underlying mechanisms of the condition. Additional resources and information about cleidocranial dysplasia can be found through organizations such as the Genetic and Rare Diseases Information Center (GARD), OMIM, and PubMed. These resources provide valuable information, references, and articles for patients, healthcare providers, and researchers to learn more about cleidocranial dysplasia.

The average length of the portion of a doctor appointment in which the patient actually sees the doctor is up from previous years, rising by about 12 seconds per year, according to Reuters. However, 60% of physicians report dissatisfaction with the amount of time they spend with their patients, athenaInsight Many doctors now spend more time on paperwork than seeing patients, and a primary care physician who spends 5 minutes of face-to-face time with a patient will spend another 19.3 minutes, on average, working on that patient’s electronic health records (EHRs).

Frequency

The frequency of cleidocranial dysplasia (CCD) is estimated to be 1 in 1 million births.

CCD is a rare genetic condition, and its occurrence is believed to be underdiagnosed due to its variable presentation and mild symptoms in some cases.

CCD is caused by mutations in the RUNX2 gene, which is responsible for the formation of bones and teeth. Mutations in this gene lead to incomplete bone and tooth development, resulting in the characteristic features of CCD.

The frequency of CCD may vary among different populations and ethnic groups. Studies have reported a higher prevalence of CCD in certain populations, such as South Africa, where the frequency is estimated to be around 1 in 100,000 births.

Due to the rarity of CCD, there are limited resources and research studies available on this condition. However, there are several articles and scientific studies on CCD available on PubMed and other scientific databases.

Additional information and resources on CCD can be found on websites such as OMIM (Online Mendelian Inheritance in Man) and the Cleidocranial Dysplasia Support and Advocacy Center.

Genetic testing is available for individuals suspected to have CCD. Testing can confirm the diagnosis and identify the specific mutation in the RUNX2 gene. This information can aid in genetic counseling and family planning.

ClinicalTrials.gov may have clinical trials and research studies focused on CCD. These studies aim to improve the understanding and management of this condition.

It is important for individuals with CCD and their families to seek medical attention and support from a healthcare provider experienced in rare genetic conditions. The patient’s clinical presentation and specific symptoms will guide the treatment plan, which may include dental care, orthopedic interventions, and other supportive measures.

Overall, cleidocranial dysplasia is a rare genetic condition with limited research and resources available. However, advances in genetic testing and research offer hope for a better understanding and management of this condition in the future.

Causes

Cleidocranial dysplasia (CCD) is a rare genetic condition that is caused by mutations in the RUNX2 gene. This gene provides instructions for making a protein that is essential for the development of bones and teeth.

CCD has several other names, including cleidocranial dysostosis, cleidocranial dysplasia syndrome, and Marie-Sainton disease. It is characterized by the incomplete development of bones, particularly those in the skull and collarbone.

CCD is inherited in an autosomal dominant pattern, which means that a person only needs to inherit one mutated copy of the RUNX2 gene from either parent to develop the condition.

Most cases of CCD are caused by new mutations in the RUNX2 gene, rather than being inherited from a parent. However, affected individuals have a 50% chance of passing the mutated gene on to each of their children.

In rare cases, CCD may be associated with other genetic diseases and syndromes. Additional genetic testing may be recommended to identify any other underlying conditions.

PubMed, OMIM, and other online resources provide more information about the cause and genetics of CCD. Scientific articles and clinicaltrials.gov may also be good sources to learn about current research and studies on CCD and associated diseases.

Advocacy organizations and support groups can also provide valuable information and resources for patients and their families affected by cleidocranial dysplasia.

Overall, learning more about the genetic causes of Cleidocranial dysplasia can provide a better understanding of the condition and help improve patient care and support.

Inheritance

Cleidocranial dysplasia (CCD) is a rare genetic condition caused by mutations in the gene called RUNX2. The inheritance pattern of CCD is autosomal dominant, which means that an affected individual has a 50% chance of passing the condition on to each of their children. In some cases, CCD may also occur sporadically, without a family history of the condition.

CCD is associated with a variety of clinical features, which can vary greatly among affected individuals. These features include abnormally shaped collarbones (cleido-) and delayed closure of the spaces between the bones of the skull (-cranial), leading to the characteristic appearance of a wide, open fontanelle (soft spot) and larger-than-usual parietal bones (the top and sides of the skull).

Other common features of CCD include dental abnormalities, such as delayed eruption of permanent teeth, extra teeth, and abnormal tooth development. Infants and young children with CCD often have delayed speech and motor skills, but their growth and development are usually otherwise normal.

Genetic testing is available to confirm a diagnosis of CCD. A genetic counselor or other healthcare professional can provide more information and support for individuals and families considering genetic testing. Additionally, there are resources available for individuals and families affected by CCD, such as advocacy organizations, support groups, and online communities.

It is important for individuals with CCD and their families to work closely with a healthcare team that includes doctors, dentists, and other healthcare professionals experienced in treating and managing the condition. Regular monitoring and additional testing may be necessary to address the specific needs and challenges associated with CCD.
