Progressive pseudorheumatoid dysplasia (PPD) is a rare genetic condition associated with the CCN6 gene. It causes degeneration and abnormal development of the joints, leading to progressive joint stiffness and pain. While the exact frequency of the condition is unknown, it is considered to be a rare disease.

PPD typically presents in childhood, with symptoms appearing during early adolescence. The condition is characterized by progressive joint deformity, limited joint mobility, and pain. It often affects the small joints of the hands, hips, and knees, resulting in difficulties with activities such as walking, gripping objects, and climbing stairs.

The inheritance of PPD follows an autosomal recessive pattern, which means that both parents must carry a copy of the mutated gene in order for their child to be affected. Genetic testing can be used to confirm the diagnosis of PPD in individuals with suspected symptoms or a family history of the condition.

Researchers have identified mutations in the CCN6 gene as the primary cause of PPD. This gene provides instructions for the production of the protein CCN6, which is involved in the maintenance of joint health. Mutations in the CCN6 gene disrupt the normal function of the protein, leading to the development of PPD.

Currently, there is no cure for PPD. Treatment focuses on managing symptoms, improving mobility, and preventing further joint damage. Physical therapy, pain management strategies, and assistive devices can be beneficial for individuals living with PPD. Regular monitoring and support from healthcare professionals can help patients navigate the challenges of the condition.

For additional information and resources on progressive pseudorheumatoid dysplasia, patients and their families can consult reputable scientific articles, such as those available on PubMed and OMIM. Support and advocacy groups may also provide valuable support and information to individuals and families affected by PPD.

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

Progressive pseudorheumatoid dysplasia is a rare genetic condition associated with the CCN6 gene. It is a childhood-onset disease characterized by progressive joint degeneration and other skeletal problems.

This condition is very rare, with only a few cases reported in the scientific literature. The exact frequency of progressive pseudorheumatoid dysplasia is not well known.

Information about the frequency of this condition can be found in the Online Mendelian Inheritance in Man (OMIM) catalog. Additional articles and references on this topic can be found on PubMed, a database of scientific articles.

Genetic testing can be done to confirm the diagnosis of progressive pseudorheumatoid dysplasia. This testing may also help identify the specific mutations in the CCN6 gene that are causing the condition.

Progressive pseudorheumatoid dysplasia is inherited in an autosomal recessive manner. This means that both parents must carry a mutation in the CCN6 gene in order for their child to inherit the condition.

Support and advocacy resources can be helpful for those living with progressive pseudorheumatoid dysplasia. Organizations like the Pseudorheumatoid Dysplasia Advocacy and Resource Center provide information and support to patients and their families.

Causes

Progressive pseudorheumatoid dysplasia is a rare genetic condition with autosomal recessive inheritance. It is caused by mutations in the CCN6 gene, also known as the WISP3 gene. This gene provides instructions for making a protein that is involved in the normal development and maintenance of cartilage and other connective tissues in the body.

In individuals with progressive pseudorheumatoid dysplasia, mutations in the CCN6 gene lead to the production of an abnormal protein or to the production of no protein at all. This protein abnormality disrupts the normal development and maintenance of cartilage, causing the signs and symptoms of the condition.

Progressive pseudorheumatoid dysplasia is a progressive condition, meaning that the signs and symptoms worsen over time. It typically begins in early childhood, with affected individuals experiencing joint pain and stiffness. As the condition progresses, joint deformities and limited mobility can occur. Additionally, individuals with progressive pseudorheumatoid dysplasia may develop premature osteoarthritis, which is a degenerative joint disease.

The frequency of progressive pseudorheumatoid dysplasia is unknown, but it is considered a rare condition. Most cases have been reported in individuals of Middle Eastern or Mediterranean descent.

Learn more about the gene associated with Progressive pseudorheumatoid dysplasia

Progressive pseudorheumatoid dysplasia (PPD) is a rare genetic condition that causes progressive joint degeneration in childhood. The condition is caused by mutations in the CCN6 gene, also known as WISP3.

The CCN6 gene is responsible for producing a protein that is important for the normal development and maintenance of joints. Mutations in this gene result in the production of an abnormal protein, which leads to the progressive destruction of cartilage and the development of joint problems in patients with PPD.

To learn more about the CCN6 gene and its association with progressive pseudorheumatoid dysplasia, there are several scientific articles and resources available.

One such resource is the Online Mendelian Inheritance in Man database, which provides information on the genetic basis of inherited diseases. The OMIM entry for PPD (OMIM #208230) includes additional information on the CCN6 gene and its role in causing the condition.

Another useful resource is the PubMed database, which contains a vast collection of scientific articles. Searching for “WISP3 gene” or “CCN6 gene” in PubMed will yield relevant articles on the genetic and molecular aspects of PPD.

In addition, the PPD Support and Advocacy Center provides information and support for patients and families affected by PPD. Their website offers resources and links to other organizations focused on rare diseases and genetic conditions.

By learning more about the gene associated with progressive pseudorheumatoid dysplasia, patients, families, and healthcare professionals can gain a better understanding of the condition and its inheritance.

Inheritance

Progressive pseudorheumatoid dysplasia is a rare genetic condition that affects children. It is caused by mutations in the CCN6 gene, also known as the WISP3 gene. Inheritance of this condition follows an autosomal recessive pattern, meaning that both copies of the gene must be mutated for the disease to occur.

Each parent of an affected individual carries one copy of the mutated gene, but they do not typically show any symptoms of the condition. When both parents are carriers, there is a 25% chance with each pregnancy that their child will inherit two copies of the mutated gene and develop progressive pseudorheumatoid dysplasia.

To learn more about the specific genes associated with this condition, you can search the OMIM (Online Mendelian Inheritance in Man) catalog and the PubMed database. These resources provide additional scientific articles and information about the genes involved in progressive pseudorheumatoid dysplasia.

In addition to genetic testing, the diagnosis of progressive pseudorheumatoid dysplasia is based on clinical features and radiographic findings. Common symptoms include joint pain, stiffness, and swelling, which usually begin in childhood. The condition can lead to progressive joint degeneration and other skeletal problems.

For patients and their families, it is important to seek support from advocacy organizations and medical centers that specialize in rare diseases. These resources can provide more information and connect individuals with the latest research and treatment options for progressive pseudorheumatoid dysplasia.
