Genes affected
GALR1 (HGNC:4132): (galanin receptor 1) The neuropeptide galanin elicits a range of biological effects by interaction with specific G-protein-coupled receptors. Galanin receptors are seven-transmembrane proteins shown to activate a variety of intracellular second-messenger pathways. GALR1 inhibits adenylyl cyclase via a G protein of the Gi/Go family. GALR1 is widely expressed in the brain and spinal cord, as well as in peripheral sites such as the small intestine and heart. [provided by RefSeq, Jul 2008]

The c.47C>A (p.P16Q) alteration is located in exon 1 (coding exon 1) of the GALR1 gene. This alteration results from a C to A substitution at nucleotide position 47, causing the proline (P) at amino acid position 16 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
