Description

This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 868 of the FLNA protein (p.Pro868Leu). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with FLNA-related conditions. ClinVar contains an entry for this variant (Variation ID: 2633815). 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 with a negative 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.
