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

Mar 16, 2022

The c.635G>A (p.R212Q) 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 635, causing the arginine (R) at amino acid position 212 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
