Genes affected

IL22RA2 (HGNC:14901): (interleukin 22 receptor subunit alpha 2) This gene encodes a member of the class II cytokine receptor family. The encoded soluble protein specifically binds to and inhibits interleukin 22 activity by blocking the interaction of interleukin 22 with its cell surface receptor. The encoded protein may be important in the regulation of inflammatory response, and has been implicated in the regulation of tumorigenesis in the colon. Alternative splicing results in multiple transcript variants encoding distinct isoforms. [provided by RefSeq, Jul 2013]

Ambry Genetics

Jul 20, 2022

The c.452G>A (p.R151Q) alteration is located in exon 5 (coding exon 4) of the IL22RA2 gene. This alteration results from a G to A substitution at nucleotide position 452, causing the arginine (R) at amino acid position 151 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
