Description

This sequence change replaces histidine, which is basic and polar, with leucine, which is neutral and non-polar, at codon 4248 of the USH2A protein (p.His4248Leu). This variant is present in population databases (rs145830318, gnomAD 0.04%). This variant has not been reported in the literature in individuals affected with USH2A-related conditions. ClinVar contains an entry for this variant (Variation ID: 1434666). 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 not expected to disrupt USH2A 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.
