Labcorp Genetics (formerly Invitae), Labcorp RCV001961635 SCV002248863 pathogenic not provided 2025-01-06 criteria provided, single submitter clinical testing This sequence change replaces methionine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 293 of the ABCA4 protein (p.Met293Arg). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with clinical features of ABCA4-related conditions (internal data). 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: 1469559). 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 not expected to disrupt ABCA4 protein function with a negative predictive value of 95%. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. For these reasons, this variant has been classified as Pathogenic.
