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]

Sep 15, 2021

The c.812A>C (p.E271A) alteration is located in exon 3 (coding exon 3) of the GALR1 gene. This alteration results from a A to C substitution at nucleotide position 812, causing the glutamic acid (E) at amino acid position 271 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
