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.

This sequence change replaces proline, which is neutral and non-polar, with serine, which is neutral and polar, at codon 171 of the RHO protein (p.Pro171Ser). This variant is present in population databases (rs104893794, gnomAD 0.01%). This missense change has been observed in individuals with clinical features of autosomal dominant retinitis pigmentosa (PMID: 8088850, 26962691; Invitae). ClinVar contains an entry for this variant (Variation ID: 13050). 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 expected to disrupt RHO protein function with a positive predictive value of 80%. This variant disrupts the p.Pro171 amino acid residue in RHO. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 1833777, 8253795, 29847639). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic. -
