Genes affected

IL31RA (HGNC:18969): (interleukin 31 receptor A) The protein encoded by this gene belongs to the type I cytokine receptor family. This receptor, with homology to gp130, is expressed on monocytes, and is involved in IL-31 signaling via activation of STAT-3 and STAT-5. It functions either as a monomer, or as part of a receptor complex with oncostatin M receptor (OSMR). Several alternatively spliced transcript variants encoding different isoforms have been noted for this gene.[provided by RefSeq, Jun 2011]

Collection Method: clinical testing

The c.236A>G (p.E79G) alteration is located in exon 3 (coding exon 3) of the IL31RA gene. This alteration results from a A to G substitution at nucleotide position 236, causing the glutamic acid (E) at amino acid position 79 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
