Genes affected

IL18RAP (HGNC:5989): (interleukin 18 receptor accessory protein) The protein encoded by this gene is an accessory subunit of the heterodimeric receptor for interleukin 18 (IL18), a proinflammatory cytokine involved in inducing cell-mediated immunity. This protein enhances the IL18-binding activity of the IL18 receptor and plays a role in signaling by IL18. Mutations in this gene are associated with Crohn's disease and inflammatory bowel disease, and susceptibility to celiac disease and leprosy. Alternatively spliced transcript variants of this gene have been described, but their full-length nature is not known. [provided by RefSeq, Feb 2014]

The c.953A>G (p.E318G) alteration is located in exon 9 (coding exon 7) of the IL18RAP gene. This alteration results from a A to G substitution at nucleotide position 953, causing the glutamic acid (E) at amino acid position 318 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
