The IL2RG gene, also listed as “interleukin 2 receptor subunit gamma,” is a gene located on the X chromosome. This gene is responsible for encoding the cytokine receptor common gamma chain, which plays a crucial role in regulating the immune system. Mutations or changes in this gene can result in severe combined immunodeficiency (SCID), a group of rare genetic disorders where the immune system is unable to effectively protect the body from infections.

According to PubMed, several references and articles have been published regarding the changes in the IL2RG gene and its relation to various immune conditions. The OMIM database also provides additional information on the gene and its associated diseases. With the combined resources from these databases, genetic testing can be performed to identify variant genes and provide insight into the diagnosis and treatment of immunodeficiency diseases.

Inside the cell, the IL2RG gene encodes a receptor that is shared among several cytokines, including interleukin-2, interleukin-4, interleukin-7, interleukin-9, and interleukin-15. This shared receptor, also known as the common gamma chain, is essential for the development and function of immune cells such as T and B lymphocytes and natural killer cells.

By understanding the IL2RG gene and its role in the immune system, researchers and healthcare professionals can gain valuable knowledge to better diagnose and treat patients with immunodeficiency disorders. This information can contribute to the development of targeted therapies and improve the overall health and quality of life for individuals affected by SCID and related conditions.

Genetic changes in the IL2RG gene are associated with various health conditions and diseases primarily related to the immune system. These conditions are collectively known as X-linked severe combined immunodeficiency (XSCID) or X-linked combined immunodeficiency (XCID).

Individuals with XSCID or XCID have a weakened immune system that leaves them more susceptible to infections. The IL2RG gene provides instructions for making a protein called the common gamma chain (γc). This protein is a crucial component of several receptors on immune cells, including T cells, B cells, and natural killer cells. The receptors help these immune cells respond to signals from other immune cells, regulate immune reactions, and coordinate the body’s defense against infections.

Changes in the IL2RG gene can disrupt the production or function of the common gamma chain protein, impairing the immune system’s ability to mount an effective immune response. This can lead to recurrent, severe, and often life-threatening infections.

Diagnosis of IL2RG gene-related immunodeficiency can be confirmed through genetic testing. Several resources, such as OMIM (Online Mendelian Inheritance in Man) and PubMed, provide comprehensive scientific information on the IL2RG gene and related health conditions.

Additional testing can be performed to identify specific changes or variants in the IL2RG gene. The Human Gene Mutation Database (HGMD), ClinVar, and the X-Linked SCID Registry and Catalog are valuable databases that compile data on genetic changes associated with XSCID or XCID.

Healthcare professionals may use these resources to aid in the diagnosis and management of individuals with IL2RG gene-related immunodeficiency. Furthermore, the X-Linked SCID Registry and Catalog can help researchers and clinicians stay updated on the latest articles, studies, and clinical trials related to XSCID or XCID.

In summary, genetic changes in the IL2RG gene can lead to severe combined immunodeficiency (SCID) or combined immunodeficiency (CID). These conditions weaken the immune system and increase the risk of recurrent infections. Genetic testing, along with resources such as OMIM, PubMed, HGMD, ClinVar, and the X-Linked SCID Registry and Catalog, can provide valuable information for diagnosis and management of IL2RG gene-related health conditions.

X-linked severe combined immunodeficiency

X-linked severe combined immunodeficiency (SCID) is a rare genetic disorder that affects the immune system. It is caused by mutations in the IL2RG gene, which is located on the X chromosome. This gene provides instructions for making a protein called the common gamma chain, which plays a critical role in immune cell signaling.

Individuals with X-linked SCID have a faulty common gamma chain, which leads to a severe deficiency of immune cells. As a result, they are highly susceptible to infections and often experience recurrent and severe illnesses.

The IL2RG gene is just one of several genes involved in the development and function of the immune system. Changes in other genes can also cause SCID or other combined immunodeficiency conditions. The Online Mendelian Inheritance in Man (OMIM) database is a valuable resource for information on genetic conditions, including SCID and related disorders.

Genetic testing can help identify changes in the IL2RG gene or other genes that may be associated with SCID. This testing can be done using a variety of methods, including sequencing the gene, looking for specific changes, or analyzing the protein produced by the gene. Testing may be available through specialized laboratories or as part of research studies.

The Genetic Testing Registry (GTR) is a central catalog of genetic tests and laboratories, providing information on the availability and details of specific tests. The National Center for Biotechnology Information (NCBI) provides additional resources and databases for genetic research, including PubMed, a scientific article database.

According to the OMIM database, there are several variant names for X-linked SCID, including SCIDX1, XSCID, and X-linked immunodeficiency with hyper-IgM. These names may be used interchangeably in scientific articles or medical records.

It is important for individuals with X-linked SCID or other genetic conditions to seek proper medical care and remain informed about the latest research and treatment options. This can help in managing the condition and improving overall health.
