Labcorp Genetics (formerly Invitae), Labcorp RCV005105211 SCV005815824 uncertain significance Aortic aneurysm, familial thoracic 4 2024-03-08 criteria provided, single submitter clinical testing This sequence change replaces isoleucine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 1078 of the MYH11 protein (p.Ile1078Met). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individuals with thoracic aortic aneurysm and/or dissection (PMID: 30526509; Invitae). 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 MYH11 protein function with a negative predictive value of 95%. 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.
