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.

ACMG classification

Our verdict: Pathogenic. The variant received 17 ACMG points.

• PM1: In a hotspot region, there are 9 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 1 benign, 8 uncertain in NM_000539.3
• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 125 curated pathogenic missense variants (we use a threshold of 10). The gene has 8 curated benign missense variants. Gene score misZ: 0.24182 (below the threshold of 3.09). Trascript score misZ: 1.4363 (below the threshold of 3.09). GenCC associations: The gene is linked to congenital stationary night blindness, congenital stationary night blindness autosomal dominant 1, retinitis pigmentosa 4, fundus albipunctatus, retinitis pigmentosa.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.987
• PP5: Variant 3-129528891-C-G is Pathogenic according to our data. Variant chr3-129528891-C-G is described in ClinVar as Pathogenic. ClinVar VariationId is 13037.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

For these reasons, this variant has been classified as Pathogenic. Experimental studies have shown that this missense change affects RHO function (PMID: 22791210). 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. ClinVar contains an entry for this variant (Variation ID: 13037). This missense change has been observed in individual(s) with autosomal dominant retinitis pigmentosa (PMID: 1301135, 22968130, 26962691, 31319082). In at least one individual the variant was observed to be de novo. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces proline, which is neutral and non-polar, with arginine, which is basic and polar, at codon 53 of the RHO protein (p.Pro53Arg).
