[[http://www.uniprot.org/uniprot/IL2RA_HUMAN IL2RA_HUMAN]] Genetic variations in IL2RA are associated with susceptibility to diabetes mellitus insulin-dependent type 10 (IDDM10) [MIM:[http://omim.org/entry/601942 601942]]. A multifactorial disorder of glucose homeostasis that is characterized by susceptibility to ketoacidosis in the absence of insulin therapy. Clinical fetaures are polydipsia, polyphagia and polyuria which result from hyperglycemia-induced osmotic diuresis and secondary thirst. These derangements result in long-term complications that affect the eyes, kidneys, nerves, and blood vessels.<ref>PMID:17676041</ref>  [[http://www.uniprot.org/uniprot/IL2_HUMAN IL2_HUMAN]] Note=A chromosomal aberration involving IL2 is found in a form of T-cell acute lymphoblastic leukemia (T-ALL). Translocation t(4;16)(q26;p13) with involves TNFRSF17. [[http://www.uniprot.org/uniprot/IL2RG_HUMAN IL2RG_HUMAN]] Defects in IL2RG are the cause of severe combined immunodeficiency X-linked T-cell-negative/B-cell-positive/NK-cell-negative (XSCID) [MIM:[http://omim.org/entry/300400 300400]]; also known as agammaglobulinemia Swiss type. A form of severe combined immunodeficiency (SCID), a genetically and clinically heterogeneous group of rare congenital disorders characterized by impairment of both humoral and cell-mediated immunity, leukopenia, and low or absent antibody levels. Patients present in infancy recurrent, persistent infections by opportunistic organisms. The common characteristic of all types of SCID is absence of T-cell-mediated cellular immunity due to a defect in T-cell development.<ref>PMID:8401490</ref> <ref>PMID:8299698</ref> <ref>PMID:8088810</ref> <ref>PMID:8027558</ref> <ref>PMID:7937790</ref> <ref>PMID:7668284</ref> <ref>PMID:7557965</ref> <ref>PMID:7860773</ref> <ref>PMID:8900089</ref> <ref>PMID:9150740</ref>  Defects in IL2RG are the cause of X-linked combined immunodeficiency (XCID) [MIM:[http://omim.org/entry/312863 312863]]. XCID is a less severe form of X-linked immunodeficiency with a less severe degree of deficiency in cellular and humoral immunity than that seen in XSCID.<ref>PMID:7883965</ref> <ref>PMID:9399950</ref>

[[http://www.uniprot.org/uniprot/IL2RA_HUMAN IL2RA_HUMAN]] Receptor for interleukin-2. [[http://www.uniprot.org/uniprot/IL2_HUMAN IL2_HUMAN]] Produced by T-cells in response to antigenic or mitogenic stimulation, this protein is required for T-cell proliferation and other activities crucial to regulation of the immune response. Can stimulate B-cells, monocytes, lymphokine-activated killer cells, natural killer cells, and glioma cells. [[http://www.uniprot.org/uniprot/IL2RG_HUMAN IL2RG_HUMAN]] Common subunit for the receptors for a variety of interleukins. [[http://www.uniprot.org/uniprot/IL2RB_HUMAN IL2RB_HUMAN]] Receptor for interleukin-2. This beta subunit is involved in receptor mediated endocytosis and transduces the mitogenic signals of IL2.
