Therefore, it has been classified as a Variant of Uncertain Significance. 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 FLNA protein function. This variant has not been reported in the literature in individuals affected with FLNA-related conditions. This variant is present in population databases (rs782148392, ExAC 0.002%). This sequence change replaces histidine with arginine at codon 1217 of the FLNA protein (p.His1217Arg). The histidine residue is moderately conserved and there is a small physicochemical difference between histidine and arginine.
