Labcorp Genetics (formerly Invitae), Labcorp RCV003051160 SCV003449139 uncertain significance Multiple gastrointestinal atresias 2022-10-17 criteria provided, single submitter clinical testing This sequence change replaces leucine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 159 of the TTC7A protein (p.Leu159Met). This variant is present in population databases (no rsID available, gnomAD 0.002%). This variant has not been reported in the literature in individuals affected with TTC7A-related conditions. 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 TTC7A 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.
