Variant summary
Our verdict is Pathogenic. Variant got 18 ACMG points: 18P and 0B. PM1PM2PM5PP3_StrongPP5_Very_Strong
The NM_000554.6(CRX):c.122G>A(p.Arg41Gln) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000805 in 1,614,018 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. R41W) has been classified as Pathogenic.

Leber congenital amaurosis 7;C3489532:Cone-rod dystrophy 2 Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Nov 06, 2023 | This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 41 of the CRX protein (p.Arg41Gln). This variant is present in population databases (rs61748436, gnomAD 0.007%). This missense change has been observed in individuals with autosomal dominant and autosomal recessive retinal disease (PMID: 9427255, 11748859, 24265693, 29068479, 30543658, 31215831; Invitae). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 7421). 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 CRX protein function with a positive predictive value of 80%. Experimental studies have shown that this missense change affects CRX function (PMID: 11971869). For these reasons, this variant has been classified as Pathogenic. - |
