Genes affected

GPR55 (HGNC:4511): (G protein-coupled receptor 55) This gene belongs to the G-protein-coupled receptor superfamily. The encoded integral membrane protein is a likely cannabinoid receptor. It may be involved in several physiological and pathological processes by activating a variety of signal transduction pathways. [provided by RefSeq, Aug 2013]

Ambry Genetics

Jan 04, 2022

The c.454G>A (p.G152R) alteration is located in exon 2 (coding exon 1) of the GPR55 gene. This alteration results from a G to A substitution at nucleotide position 454, causing the glycine (G) at amino acid position 152 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
