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.890A>G (p.N297S) 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 890, causing the asparagine (N) at amino acid position 297 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
