Genes affected

NPY1R (HGNC:7956): (neuropeptide Y receptor Y1) This gene belongs to the G-protein-coupled receptor superfamily. The encoded transmembrane protein mediates the function of neuropeptide Y (NPY), a neurotransmitter, and peptide YY (PYY), a gastrointestinal hormone. The encoded receptor undergoes fast agonist-induced internalization through clathrin-coated pits and is subsequently recycled back to the cell membrane. Activation of Y1 receptors may result in mobilization of intracellular calcium and inhibition of adenylate cyclase activity. [provided by RefSeq, Aug 2013]

The c.755A>G (p.K252R) alteration is located in exon 3 (coding exon 2) of the NPY1R gene. This alteration results from a A to G substitution at nucleotide position 755, causing the lysine (K) at amino acid position 252 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
