Genes affected

PNOC (HGNC:9163): (prepronociceptin) This gene encodes a preproprotein that is proteolytically processed to generate multiple protein products. These products include nociceptin, nocistatin, and orphanin FQ2 (OFQ2). Nociceptin, also known as orphanin FQ, is a 17-amino acid neuropeptide that binds to the nociceptin receptor to induce increased pain sensitivity, and may additionally regulate body temperature, learning and memory, and hunger. Another product of the encoded preproprotein, nocistatin, may inhibit the effects of nociceptin. [provided by RefSeq, Jul 2015]

The c.305G>A (p.R102Q) alteration is located in exon 3 (coding exon 2) of the PNOC gene. This alteration results from a G to A substitution at nucleotide position 305, causing the arginine (R) at amino acid position 102 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
