| [[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/I15RA_HUMAN I15RA_HUMAN]] High-affinity receptor for interleukin-15. Can signal both in cis and trans where IL15R from one subset of cells presents IL15 to neighboring IL2RG-expressing cells. Expression of different isoforms may alter or interfere with signal transduction. Isoform 5, isoform 6, isoform 7 and isoform 8 do not bind IL15. Signal transduction involves STAT3, STAT5, STAT6, JAK2 (By similarity) and SYK.<ref>PMID:8530383</ref> <ref>PMID:11714793</ref> [[http://www.uniprot.org/uniprot/IL15_HUMAN IL15_HUMAN]] Cytokine that stimulates the proliferation of T-lymphocytes.
