Genes affected

GPR161 (HGNC:23694): (G protein-coupled receptor 161) The protein encoded by this gene is an orphan G protein-coupled receptor whose ligand is unknown. This gene is overexpressed in triple-negative breast cancer, and disruption of this gene slows the proliferation of basal breast cancer cells. Therefore, this gene is a potential drug target for triple-negative breast cancer. [provided by RefSeq, Mar 2017]

ACMG classification

Verdict is Uncertain_significance. Variant got 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage

Collection Method: clinical testing

This sequence change creates a premature translational stop signal (p.Ser481Leufs*10) in the GPR161 gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 69 amino acid(s) of the GPR161 protein. This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with GPR161-related conditions. Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
