Labcorp Genetics (formerly Invitae), Labcorp RCV003531569 SCV004297624 uncertain significance Aortic valve disease 2 2023-12-09 criteria provided, single submitter clinical testing This sequence change replaces threonine, which is neutral and polar, with alanine, which is neutral and non-polar, at codon 306 of the SMAD6 protein (p.Thr306Ala). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with craniosynostosis (PMID: 27606499). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt SMAD6 protein function with a negative predictive value of 80%. 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.
