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]

Ambry Genetics

Aug 10, 2021

The c.8T>G (p.L3R) alteration is located in exon 1 (coding exon 1) of the GALR1 gene. This alteration results from a T to G substitution at nucleotide position 8, causing the leucine (L) at amino acid position 3 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
