Labcorp Genetics (formerly Invitae), Labcorp RCV001312454 SCV001502910 uncertain significance Multiple gastrointestinal atresias 2020-06-26 criteria provided, single submitter clinical testing This sequence change replaces arginine with glycine at codon 856 of the TTC7A protein (p.Arg856Gly). The arginine residue is moderately conserved and there is a moderate physicochemical difference between arginine and glycine. 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. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with TTC7A-related conditions. This variant is not present in population databases (ExAC no frequency).
