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 threonine, which is neutral and polar, with methionine, which is neutral and non-polar, at codon 58 of the RHO protein (p.Thr58Met). This variant is present in population databases (rs28933394, gnomAD 0.02%). This missense change has been observed in individual(s) with autosomal dominant retinitis pigmentosa (PMID: 20591486, 25265376). ClinVar contains an entry for this variant (Variation ID: 967490). 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: 8486634, 30977563). 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.
