Complement component 2 deficiency is a rare genetic condition that affects the immune system. It is caused by mutations in the C2 gene, which is responsible for producing a protein involved in the complement system. The complement system is a group of proteins that help the immune system fight off infections and other diseases.

Individuals with complement component 2 deficiency have a higher risk of developing certain autoimmune diseases, such as systemic lupus erythematosus. This condition can cause a wide range of symptoms and affect various organs and tissues in the body. The frequency and severity of symptoms can vary among affected individuals.

Diagnosis of complement component 2 deficiency is typically made through genetic testing. This testing can help confirm the presence of mutations in the C2 gene and provide information about the inheritance pattern of the condition. Testing may also be necessary to rule out other genetic or immunologic conditions with similar symptoms.

There is currently no cure for complement component 2 deficiency, and treatment focuses on managing the symptoms and complications associated with the condition. This can include medications to control inflammation and infection, as well as regular monitoring of organ function. Genetic testing can also help identify other family members who may be at risk of inheriting the condition.

For more information about complement component 2 deficiency, genetic testing, and other related conditions, the Center for Disease Control and Prevention (CDC) and the National Institutes of Health (NIH) provide additional resources and support. Additionally, scientific articles and references can be found on databases such as PubMed and OMIM.

In conclusion, complement component 2 deficiency is a rare genetic condition that affects the immune system. It is caused by mutations in the C2 gene and can lead to a variety of symptoms and complications. Genetic testing and additional resources can provide valuable information and support for individuals and families affected by this condition.

Just under half – 49% – of Americans get their health insurance through their employer, according to the Henry J. Kaiser Family Foundation. Another 19% of Americans are insured under Medicaid, 14% under Medicare, seven% under non-group plans and two% under other public insurers, while nine% of U.S. citizens remain uninsured.

Frequency

Complement component 2 deficiency is a rare genetic condition that affects the immune system. The frequency of this deficiency is not well documented, but it is thought to be a rare disorder.

According to the Genetic and Rare Diseases Information Center (GARD), the exact prevalence of complement component 2 deficiency in the general population is unknown. However, it is estimated to occur in less than 1 in 1 million individuals worldwide.

Complement component 2 deficiency is inherited in an autosomal recessive manner, meaning that both copies of the C2 gene in each cell have mutations. This condition can affect both males and females.

Patients with complement component 2 deficiency may experience a range of symptoms, including recurrent infections, autoimmune disorders, and other conditions associated with systemic lupus erythematosus (SLE).

More information about the frequency of complement component 2 deficiency can be found in scientific articles and research studies. The Online Mendelian Inheritance in Man (OMIM) catalog is a valuable resource for learning about the genetic causes, inheritance patterns, and clinical features associated with this condition.

In addition to OMIM, other resources such as PubMed and the National Organization for Rare Disorders (NORD) can provide additional information and support for patients and their families.

To diagnose complement component 2 deficiency, genetic testing can be performed to identify mutations in the C2 gene. This can help confirm the diagnosis and guide appropriate treatment strategies.

Causes

Complement component 2 deficiency is a rare genetic condition associated with a deficiency in the complement component 2 protein.

The complement system is an important part of the immune system that helps to defend the body against infections and diseases. It is made up of a group of proteins, including complement component 2, that work together to identify and destroy foreign invaders such as bacteria and viruses.

Complement component 2 deficiency is caused by mutations in the C2 gene, which provides instructions for making the complement component 2 protein. These mutations can lead to a decrease in the production or function of complement component 2, resulting in a deficiency in the complement system.

This genetic condition is inherited in an autosomal recessive pattern, which means that an individual must inherit two copies of the mutated C2 gene (one from each parent) in order to develop complement component 2 deficiency. Individuals who inherit only one mutated gene are known as carriers of the condition, and they typically do not experience any symptoms.

Complement component 2 deficiency is a rare condition, and its exact frequency in the general population is unknown. The condition has been reported in individuals of various ethnic backgrounds.

For more information on complement component 2 deficiency, you can visit the OMIM (Online Mendelian Inheritance in Man) database, which provides additional scientific information on the genes and diseases associated with this condition. Additional resources and support for patients and families affected by complement component 2 deficiency can be found through advocacy organizations and patient support groups.
