Labcorp Genetics (formerly Invitae), Labcorp RCV002046377 SCV002316212 uncertain significance Multiple gastrointestinal atresias 2021-09-21 criteria provided, single submitter clinical testing This sequence change replaces arginine with tyrosine at codon 803 of the TTC7A protein (p.Arg803Tyr). The arginine residue is moderately conserved and there is a moderate physicochemical difference between arginine and tyrosine. 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: "Not Available"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Not Available"). This variant has not been reported in the literature in individuals affected with TTC7A-related conditions. The frequency data for this variant in the population databases is not available, as this variant may be reported as separate entries in the ExAC database.
