Genes affected

RHO (HGNC:10012): (rhodopsin) The protein encoded by this gene is found in rod cells in the back of the eye and is essential for vision in low-light conditions. The encoded protein binds to 11-cis retinal and is activated when light hits the retinal molecule. Defects in this gene are a cause of congenital stationary night blindness.

The RHO c.316G>A variant was identified in an individual with retinitis pigmentosa with a presumed dominant inheritance pattern. Through a review of available evidence we were able to apply the following criteria: PM2, PP3, PP1-S, PS3. Based on this evidence we have classified this variant as Pathogenic. -

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 106 of the RHO protein (p.Gly106Arg). This variant is present in population databases (rs104893773, gnomAD 0.01%). This missense change has been observed in individuals with autosomal dominant retinitis pigmentosa (PMID: 1301135, 8905849, 11094174, 28559085). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 13038). 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 expected to disrupt RHO protein function with a positive predictive value of 95%. Experimental studies are conflicting or provide insufficient evidence to determine the effect of this variant on RHO function (PMID: 24520188). For these reasons, this variant has been classified as Pathogenic. -
