Genes affected

RGS9 (HGNC:10004): (regulator of G protein signaling 9) This gene encodes a member of the RGS family of GTPase activating proteins that function in various signaling pathways by accelerating the deactivation of G proteins. This protein is anchored to photoreceptor membranes in retinal cells and deactivates G proteins in the rod and cone phototransduction cascades. Mutations in this gene result in bradyopsia. Multiple transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Sep 2009]

Pathogenic, criteria provided, single submitter	clinical testing	Invitae	Sep 21, 2023	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. 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%). ClinVar contains an entry for this variant (Variation ID: 5862). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt RGS9 protein function. Experimental studies have shown that this missense change affects RGS9 function (PMID: 14702087). For these reasons, this variant has been classified as Pathogenic. -
