Description

This variant has not been reported in the literature in individuals affected with FKTN-related conditions. This sequence change replaces phenylalanine, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 368 of the FKTN protein (p.Phe368Leu). This variant is present in population databases (rs374381691, gnomAD 0.04%). ClinVar contains an entry for this variant (Variation ID: 861579). 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 expected to disrupt FKTN 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.
