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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 05, 2023The c.323G>A (p.S108N) 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 323, causing the serine (S) at amino acid position 108 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
