This sequence change replaces tryptophan, which is neutral and slightly polar, with arginine, which is basic and polar, at codon 299 of the RGS9 protein (p.Trp299Arg). This variant is present in population databases (rs121908449, gnomAD 0.02%). This missense change has been observed in individuals with bradyopsia and/or cone dysfunction (PMID: 14702087, 17826834, 19818506). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 5862). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt RGS9 protein function with a negative predictive value of 80%. Experimental studies have shown that this missense change affects RGS9 function (PMID: 14702087). For these reasons, this variant has been classified as Pathogenic. -
