IKBKG

IKBKG (also known as Inhibitor of Nuclear Factor Kappa B Kinase Subunit Gamma) is a gene that encodes the NF-kappa B essential modulator (NEMO) protein. This gene is located on the X chromosome and is involved in the activation of the NF-kappa B protein complex. Mutations in this gene can lead to several immune system disorders, including Incontinentia Pigmenti, Ectodermal Dysplasia and Immunodeficiency.

Function

The IKBKG gene provides instructions for making a protein called NEMO. This protein is a part of the I-kappa B kinase complex that activates the NF-kappa B protein complex. The NF-kappa B complex plays a key role in the immune system, helping to regulate the activity of genes involved in immune responses and inflammation.

Clinical Significance

Mutations in the IKBKG gene can lead to several immune system disorders. These include:

• Incontinentia Pigmenti: This is a condition that affects the skin and other body systems. It is caused by mutations in the IKBKG gene that result in a nonfunctional NEMO protein. This disrupts the activation of the NF-kappa B complex, leading to the characteristic features of this disorder.

• Ectodermal Dysplasia: This is a group of conditions characterized by abnormal development of ectodermal tissues including the skin, hair, nails, teeth, and sweat glands. Some forms of ectodermal dysplasia are caused by mutations in the IKBKG gene.

• Immunodeficiency: Certain types of immunodeficiency, such as X-linked ectodermal dysplasia and immunodeficiency (EDA-ID), are caused by mutations in the IKBKG gene. These conditions are characterized by recurrent infections, abnormal development of ectodermal tissues, and other health problems.
