Variant summary

Our verdict is Pathogenic. The variant received 17 ACMG points: 17P and 0B. PM1 PM2 PM5 PP2 PP3_Moderate PP5_Very_Strong

The NM_000539.3(RHO):​c.266G>A​(p.Gly89Asp) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Pathogenic (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G89R) has been classified as Likely pathogenic.

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 7 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 5 uncertain in NM_000539.3
• PM2: Very rare variant in population databases, with high coverage
• PM5: Other missense variant is known to change same aminoacid residue: Variant chr3-129528998-G-C is described in ClinVar as Likely_pathogenic. ClinVar VariationId is 636083.Status of the report is no_assertion_criteria_provided, 0 stars.
• 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, 0.912
• PP5: Variant 3-129528999-G-A is Pathogenic according to our data. Variant chr3-129528999-G-A is described in ClinVar as Pathogenic. ClinVar VariationId is 13021.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
