Labcorp Genetics (formerly Invitae), Labcorp RCV002648173 SCV003522773 pathogenic not provided 2022-08-20 criteria provided, single submitter clinical testing For these reasons, this variant has been classified as Pathogenic. 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 ABCA4 protein function. This missense change has been observed in individual(s) with Stargardt disease (PMID: 23882696). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. It has also been observed to segregate with disease in related individuals. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces glutamic acid, which is acidic and polar, with glycine, which is neutral and non-polar, at codon 955 of the ABCA4 protein (p.Glu955Gly).
