Labcorp Genetics (formerly Invitae), Labcorp RCV002018074 SCV002299756 uncertain significance Aortic valve disease 2 2023-12-30 criteria provided, single submitter clinical testing This sequence change replaces arginine, which is basic and polar, with glycine, which is neutral and non-polar, at codon 83 of the SMAD6 protein (p.Arg83Gly). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This variant has not been reported in the literature in individuals affected with SMAD6-related conditions. ClinVar contains an entry for this variant (Variation ID: 1509667). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be tolerated. 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.
