	==Etiology and Genetics==		==Etiology and Genetics==
	XMEN disease is caused by mutations in the ''MAGT1'' gene, which is located on the X chromosome. The ''MAGT1'' gene encodes a magnesium transporter protein that plays a crucial role in magnesium homeostasis within cells, including the proper functioning of the immune system. Mutations in this gene lead to a deficiency in intracellular magnesium, which is critical for the activation of the [[tyrosine kinase]] signaling pathway, a pathway essential for the development and function of [[T cells]]. This deficiency impairs the body's ability to fight off certain infections and may increase the risk of developing [[neoplasia]], or abnormal tissue growths.
