Variant summary

Our verdict is Benign. Variant got -12 ACMG points: 0P and 12B. BP4_Strong BA1

The NM_004224.3(GPR50):c.1816A>G(p.Ile606Val) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.45 in 110,801 control chromosomes in the GnomAD database, including 9,053 homozygotes. There are 14,558 hemizygotes in GnomAD. In-silico tool predicts a benign outcome for this variant. 14/19 in silico tools predict a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another nucleotide change resulting in same amino acid change has been previously reported as Likely benignin UniProt.

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]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=2.012317E-5).
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.577 is higher than 0.05.
