Description

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) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on LRRK2 protein function. This variant has not been reported in the literature in individuals affected with LRRK2-related conditions. This variant is present in population databases (rs201614703, gnomAD 0.002%). This sequence change replaces methionine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 2155 of the LRRK2 protein (p.Met2155Val). 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.
