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]

Collection Method: clinical testing

The c.532T>C (p.C178R) alteration is located in exon 2 (coding exon 2) of the GPR50 gene. This alteration results from a T to C substitution at nucleotide position 532, causing the cysteine (C) at amino acid position 178 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
