Description

This sequence change replaces arginine with cysteine at codon 1148 of the ATP13A2 protein (p.Arg1148Cys). The arginine residue is weakly conserved and there is a large physicochemical difference between arginine and cysteine. This variant is present in population databases (rs759327218, ExAC 0.009%). This variant has not been reported in the literature in individuals affected with ATP13A2-related conditions. 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 ATP13A2 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.
