RCV001228298 | SCV001400693 | pathogenic | not provided | 2023-12-11 | criteria provided, single submitter | clinical testing | This sequence change replaces valine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 373 of the CNGA3 protein (p.Val373Met). This variant is present in population databases (rs552553452, gnomAD 0.02%). This missense change has been observed in individual(s) with clinical features of achromatopsia (PMID: 35332618; Invitae). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. ClinVar contains an entry for this variant (Variation ID: 866006). 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 CNGA3 protein function with a positive predictive value of 95%. For these reasons, this variant has been classified as Pathogenic. |
