Variant summary
Our verdict is Pathogenic. Variant got 20 ACMG points: 20P and 0B. PS1PM1PM2PP3_StrongPP5_Very_Strong
The NM_014249.4(NR2E3):c.166G>A(p.Gly56Arg) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000019 in 1,583,018 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. 9/14 in silico tools predict a damaging outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★★). Another nucleotide change resulting in the same amino acid substitution has been previously reported as Pathogenic in Lovd.

The variant is not observed in the gnomAD v2.1.1 dataset. Predicted Consequence/Location: Missense variant In silico tool predictions suggest damaging effect of the variant on gene or gene product [REVEL: 0.56 (>=0.6, sensitivity 0.68 and specificity 0.92); 3Cnet: 0.93 (>=0.6, sensitivity 0.72 and precision 0.9)]. Same nucleotide change resulting in same amino acid change has been previously reported as pathogenic/likely pathogenic with strong evidence (ClinVar ID: VCV000005533 /PMID: 17564971). The variant has been reported to co-segregate with the disease in at least 7 similarly affected relatives/individuals in at least two unrelated families (PMID: 26910043). Therefore, this variant is classified as Pathogenic according to the recommendation of ACMG/AMP guideline. -

Published functional studies demonstrate a damaging effect (impact on DNA binding and dimerization of transcription factor NR2E3) (PMID: 19823680, 27013732); Not observed at significant frequency in large population cohorts (gnomAD); This variant is associated with the following publications: (PMID: 19006237, 26910043, 22661467, 17982421, 32037395, 19898638, 27013732, 32531858, 29034877, 33576794, 30718709, 25326637, 33807610, 31054281, 24938718, 17564971, 19823680) -

This sequence change replaces glycine with arginine at codon 56 of the NR2E3 protein (p.Gly56Arg). The glycine residue is highly conserved and there is a moderate physicochemical difference between glycine and arginine. This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individuals with autosomal dominant retinitis pigmentosa (PMID: 17564971, 17982421, 19006237, 26910043). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 5533). 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 NR2E3 protein function with a positive predictive value of 80%. Experimental studies have shown that this missense change affects NR2E3 function (PMID: 19006237, 19823680). For these reasons, this variant has been classified as Pathogenic. -
