Labcorp Genetics (formerly Invitae), Labcorp RCV001974862 SCV002208994 uncertain significance Aortic valve disease 2 2020-11-02 criteria provided, single submitter clinical testing 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 SMAD6-related conditions. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate insufficient coverage at this position in the ExAC database. This sequence change replaces arginine with cysteine at codon 198 of the SMAD6 protein (p.Arg198Cys). The arginine residue is highly conserved and there is a large physicochemical difference between arginine and cysteine. 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.
