Labcorp Genetics (formerly Invitae), Labcorp RCV003059241 SCV003334953 uncertain significance Frontotemporal dementia and/or amyotrophic lateral sclerosis 4 2022-04-01 criteria provided, single submitter clinical testing 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. 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 TBK1 protein function. This variant has not been reported in the literature in individuals affected with TBK1-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 255 of the TBK1 protein (p.Gly255Arg).
