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

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The c.58T>A (p.S20T) alteration is located in exon 2 (coding exon 1) of the JAK3 gene. This alteration results from a T to A substitution at nucleotide position 58, causing the serine (S) at amino acid position 20 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
