Genes affected
JAK3 (HGNC:6193): (Janus kinase 3) The protein encoded by this gene is a member of the Janus kinase (JAK) family of tyrosine kinases involved in cytokine receptor-mediated intracellular signal transduction. It is predominantly expressed in immune cells and transduces a signal in response to its activation via tyrosine phosphorylation by interleukin receptors. Mutations in this gene are associated with autosomal SCID (severe combined immunodeficiency disease). [provided by RefSeq, Jul 2008]
JAK3 Gene-Disease associations (from GenCC):
  • T-B+ severe combined immunodeficiency due to JAK3 deficiency
