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]

(HGNC:):

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.
