This sequence change replaces threonine, which is neutral and polar, with methionine, which is neutral and non-polar, at codon 1357 of the USH2A protein (p.Thr1357Met). This variant is present in population databases (rs201190539, gnomAD 0.1%). This missense change has been observed in individual(s) with USH2A-related conditions (PMID: 23967202, 33946315, 35114279). ClinVar contains an entry for this variant (Variation ID: 550393). 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 expected to disrupt USH2A protein function with a positive predictive value of 95%. 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.
