Genes affected
GPR50 (HGNC:4506): (G protein-coupled receptor 50) This gene product belongs to the G-protein coupled receptor 1 family. Even though this protein shares similarity with the melatonin receptors, it does not bind melatonin, however, it inhibits melatonin receptor 1A function through heterodimerization. Polymorphic variants of this gene have been associated with bipolar affective disorder in women. [provided by RefSeq, Jan 2010]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 09, 2024The c.655C>A (p.R219S) alteration is located in exon 2 (coding exon 2) of the GPR50 gene. This alteration results from a C to A substitution at nucleotide position 655, causing the arginine (R) at amino acid position 219 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
