Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine RCV000612144 SCV000712289 uncertain significance not specified 2016-06-24 criteria provided, single submitter clinical testing The p.Ile154Val variant in TPM1 has not been previously reported in individuals with cardiomyopathy or in large population studies. Computational prediction too ls and conservation analysis do not provide strong support for or against an imp act to the protein. In summary, the clinical significance of the p.Ile154Val var iant is uncertain.

Invitae RCV001066540 SCV001231554 uncertain significance Hypertrophic cardiomyopathy 2023-05-10 criteria provided, single submitter clinical testing 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. 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 disruptive. ClinVar contains an entry for this variant (Variation ID: 505158). This variant has not been reported in the literature in individuals affected with TPM1-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces isoleucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 154 of the TPM1 protein (p.Ile154Val).
