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]

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. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with RGS9-related conditions. This variant is present in population databases (rs753988401, ExAC 0.001%). This sequence change replaces asparagine with isoleucine at codon 29 of the RGS9 protein (p.Asn29Ile). The asparagine residue is moderately conserved and there is a large physicochemical difference between asparagine and isoleucine. -
