Variant summary

Our verdict is Pathogenic. Variant got 18 ACMG points: 18P and 0B. PM1PM2PM5PP3_StrongPP5_Very_Strong

The NM_000539.3(RHO):​c.568G>A​(p.Asp190Asn) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000137 in 1,461,798 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. D190G) has been classified as 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.

This sequence change replaces aspartic acid, which is acidic and polar, with asparagine, which is neutral and polar, at codon 190 of the RHO protein (p.Asp190Asn). This variant is present in population databases (rs104893779, gnomAD 0.006%). This missense change has been observed in individual(s) with autosomal dominant retinitis pigmentosa (PMID: 1765377, 19085385). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 13023). 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 not expected to disrupt RHO protein function with a negative predictive value of 80%. Experimental studies have shown that this missense change affects RHO function (PMID: 22252712, 23625926, 24520188). For these reasons, this variant has been classified as Pathogenic. -
