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]

The c.778T>C (p.C260R) alteration is located in exon 7 (coding exon 7) of the IL31RA gene. This alteration results from a T to C substitution at nucleotide position 778, causing the cysteine (C) at amino acid position 260 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
