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 glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 181 of the RHO protein (p.Glu181Lys). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with autosomal dominant retinitis pigmentosa (PMID: 1833777, 29068140). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 196282). 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 have shown that this missense change affects RHO function (PMID: 8253795, 19913029). For these reasons, this variant has been classified as Pathogenic. -

The variant is not observed in the gnomAD v2.1.1 dataset. Predicted Consequence/Location: The variant is located in a mutational hot spot and/or well-established functional domain in which established pathogenic variants have been reported. Missense changes are a common disease-causing mechanism. In silico tool predictions suggest damaging effect of the variant on gene or gene product [REVEL: 0.84 (>=0.6, sensitivity 0.68 and specificity 0.92)]. Same nucleotide change resulting in same amino acid change has been previously reported as pathogenic/likely pathogenic with strong evidence (ClinVar ID: VCV000196282 /PMID: 1833777). Therefore, this variant is classified as Pathogenic according to the recommendation of ACMG/AMP guideline. -

The RHO c.541G>A variant is predicted to result in the amino acid substitution p.Glu181Lys. This variant has been reported many times as causative for autosomal dominant retinitis pigmentosa (see for examples: Dryja et al. 1991. PubMed ID: 1833777; Sohocki et al. 2001. PubMed ID: 11139241; Eisenberger et al. 2013. PubMed ID: 24265693: Table S4, Panneman et al. 2023. PubMed ID: 36819107). This variant has not been reported in the large population database gnomAD, indicating this variant is rare. This variant has been classified as pathogenic by multiple independent submitters to the ClinVar database (https://www.ncbi.nlm.nih.gov/clinvar/variation/196282). Given the evidence, we interpret this variant as pathogenic for autosomal dominant disease. -
