Description

This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 1055 of the ABCA4 protein (p.Arg1055Trp). This variant is present in population databases (rs61752412, gnomAD 0.06%). This missense change has been observed in individual(s) with Stargardt disease (PMID: 11385708, 19265867). ClinVar contains an entry for this variant (Variation ID: 99200). 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. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
