GeneDx RCV001768647 SCV001992463 uncertain significance not provided 2020-01-03 criteria provided, single submitter clinical testing Identified in association with cardiomyopathy in published literature (Chanavat et al., 2016); Not observed in large population cohorts (Lek et al., 2016); In silico analysis, which includes protein predictors and evolutionary conservation, supports a deleterious effect; This variant is associated with the following publications: (PMID: 26688388)
Labcorp Genetics (formerly Invitae), Labcorp RCV002032829 SCV002179394 uncertain significance Hypertrophic cardiomyopathy 2; Dilated cardiomyopathy 1D; Cardiomyopathy, familial restrictive, 3 2024-10-30 criteria provided, single submitter clinical testing This sequence change replaces lysine, which is basic and polar, with glutamic acid, which is acidic and polar, at codon 167 of the TNNT2 protein (p.Lys167Glu). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with clinical features of TNNT2-related conditions (PMID: 26688388). ClinVar contains an entry for this variant (Variation ID: 1305440). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt TNNT2 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.
