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 variant is observed at an extremely low frequency in the gnomAD v2.1.1 dataset (total allele frequency: <0.001%). Predicted Consequence/Location: Missense changes are a common disease-causing mechanism. In silico tool predictions suggest damaging effect of the variant on gene or gene product [REVEL: 0.62 (>=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: VCV000013014 /PMID: 2215617 /3billion dataset). Different missense changes at the same codon (p.Pro347Ala, p.Pro347Arg, p.Pro347Gln, p.Pro347Ser, p.Pro347Thr) have been reported as pathogenic/likely pathogenic with strong evidence (ClinVar ID: VCV000013015, VCV000013032, VCV000013053, VCV001070044, VCV002203439 /PMID: 11139241, 1840561, 2215617, 7633434, 8088850). Therefore, this variant is classified as Pathogenic according to the recommendation of ACMG/AMP guideline. -

Collection Method: clinical testing

This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 347 of the RHO protein (p.Pro347Leu). This variant is present in population databases (rs29001566, gnomAD 0.0008%). This missense change has been observed in individuals with autosomal dominant retinitis pigmentosa (PMID: 2215617, 25221422). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 13014). 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 95%. For these reasons, this variant has been classified as Pathogenic. -

The RHO c.1040C>T variant is predicted to result in the amino acid substitution p.Pro347Leu. This variant has been reported as causative for autosomal dominant retinitis pigmentosa (see for examples Dryja et al. 1990. PubMed ID: 2215617; Yang et al. 2014. PubMed ID: 25221422; Ge et al. 2015. PubMed ID: 26667666). Alternate substitutions of this amino acid (p.Pro347Ala, p.Pro347Gln. p.Pro347Thr, and p.Pro347Ser) have also been documented causative for retinitis pigmentosa, and in silico studies suggest that variants of the p.Pro347 residue affect cellular trafficking and protein interaction (Rakoczy et al. 2010. PubMed ID: 21094163). This variant is reported in 0.00077% of alleles in individuals of European (Non-Finnish) descent in gnomAD. Given the evidence, we interpret this variant as pathogenic. -
