Genes affected

GALR3 (HGNC:4134): (galanin receptor 3) The neuropeptide galanin modulates a variety of physiologic processes including cognition/memory, sensory/pain processing, hormone secretion, and feeding behavior. The human galanin receptors are G protein-coupled receptors that functionally couple to their intracellular effector through distinct signaling pathways. GALR3 is found in many tissues and may be expressed as 1.4-, 2.4-, and 5-kb transcripts [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.395C>T (p.A132V) alteration is located in exon 2 (coding exon 2) of the GALR3 gene. This alteration results from a C to T substitution at nucleotide position 395, causing the alanine (A) at amino acid position 132 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
