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]

The c.1466T>G (p.V489G) alteration is located in exon 8 (coding exon 5) of the GPR161 gene. This alteration results from a T to G substitution at nucleotide position 1466, causing the valine (V) at amino acid position 489 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
