The ZAP70 gene, also known as Zeta-chain-associated protein 70, is a gene that plays a crucial role in the functioning of the immune system. It is responsible for encoding a protein called ZAP70, which is essential for the activation of T cells.

Research on the ZAP70 gene has been extensively documented in scientific literature, with numerous studies available on databases such as PubMed. These publications provide valuable information on the various variants and changes in the ZAP70 gene, as well as its role in different genetic immunodeficiency conditions.

Testing for ZAP70 gene mutations is available through various genetic testing resources and clinics. This testing can help diagnose severe immunodeficiency diseases such as ZAP70-related combined immunodeficiency. Additional information on these conditions can be found in the OMIM gene catalog, as well as in other health resources.

Health Conditions Related to Genetic Changes

Genetic changes in the ZAP70 gene are related to a condition known as Zap70-related severe combined immunodeficiency (SCID). This scientific condition is characterized by a severe impairment of the immune system, leading to recurrent and severe infections. Individuals with Zap70-related SCID have mutations in the ZAP70 gene that prevent the immune system from functioning properly.

In addition to Zap70-related SCID, changes in the ZAP70 gene can also be associated with other health conditions. These include:

• ZAP70-related autoimmune disorders: Some individuals with genetic changes in the ZAP70 gene may develop autoimmune disorders, where the immune system mistakenly attacks the body’s own cells and tissues.
• Other immunodeficiency disorders: Changes in the ZAP70 gene can also be linked to other forms of immunodeficiency, where the immune system is weakened and unable to protect against infections.

To learn more about these conditions and the genetic changes in the ZAP70 gene, you can refer to the following resources:

ZAP70-related severe combined immunodeficiency

ZAP70-related severe combined immunodeficiency (SCID) is a genetic immunodeficiency disorder caused by changes in the ZAP70 gene. SCID is a group of conditions that affects the immune system, making it difficult for individuals to fight off infections. ZAP70-related SCID is one specific form of SCID that is related to mutations in the ZAP70 gene.

The ZAP70 gene provides instructions for making a protein called Zeta-chain-associated protein kinase 70. This protein plays a critical role in immune cell signaling. Mutations in the ZAP70 gene result in a non-functional or absent ZAP70 protein. Without this protein, the immune system is unable to respond to infections properly.

Individuals with ZAP70-related SCID typically present with severe infections in the first few months of life. These infections can be life-threatening and may recur frequently. Common symptoms of ZAP70-related SCID include persistent diarrhea, failure to thrive, and recurrent respiratory infections. Without treatment, affected individuals are at high risk of developing serious complications from these infections.

Diagnosis of ZAP70-related SCID is made through genetic testing. This testing can identify changes in the ZAP70 gene that are associated with the condition. In addition to genetic testing, other laboratory tests, such as immunological testing, can help confirm the diagnosis.

There are currently no specific treatments for ZAP70-related SCID. Management of the condition typically involves preventing and controlling infections through the use of antibiotics and immunoglobulin replacements. Hematopoietic stem cell transplantation is considered the only curative treatment option for ZAP70-related SCID.

For more information on ZAP70-related severe combined immunodeficiency, additional resources can be found in scientific databases such as PubMed and OMIM. These databases provide access to articles, genetic variant information, and references to other related diseases. The Online Mendelian Inheritance in Man (OMIM) catalog and the GeneReviews database are also valuable resources for information on ZAP70-related SCID. These resources contain detailed clinical and genetic information, as well as references to scientific articles and testing resources.

In conclusion, ZAP70-related severe combined immunodeficiency is a genetic condition caused by changes in the ZAP70 gene. It is characterized by severe immunodeficiency, leading to recurrent and life-threatening infections. Genetic testing and immunological testing can aid in the diagnosis of ZAP70-related SCID. Management of the condition involves preventing and treating infections, and hematopoietic stem cell transplantation is the only curative treatment option.
