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.

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. This variant disrupts the p.Arg135 amino acid residue in RHO. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 1862076, 18175313). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. This variant has been reported to have conflicting or insufficient data to determine the effect on RHO protein function (PMID: 9538004, 2573063, 8099498). This variant has not been reported in the literature in individuals with RHO-related conditions. This variant is present in population databases (rs104893774, ExAC 0.001%). This sequence change replaces arginine with glutamine at codon 135 of the RHO protein (p.Arg135Gln). The arginine residue is highly conserved and there is a small physicochemical difference between arginine and glutamine. -
