Labcorp Genetics (formerly Invitae), Labcorp RCV001972206 SCV002208016 uncertain significance Multiple gastrointestinal atresias 2022-05-29 criteria provided, single submitter clinical testing This sequence change replaces methionine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 654 of the TTC7A protein (p.Met654Val). This variant is present in population databases (rs750008360, gnomAD 0.003%). This variant has not been reported in the literature in individuals affected with TTC7A-related conditions. ClinVar contains an entry for this variant (Variation ID: 1435311). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The valine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect 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.
