GeneDx RCV000433716 SCV000529520 likely benign not specified 2016-07-06 criteria provided, single submitter clinical testing This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease.
Invitae RCV002522372 SCV003454344 uncertain significance Hypertrophic cardiomyopathy 2; Dilated cardiomyopathy 1D; Cardiomyopathy, familial restrictive, 3 2022-10-05 criteria provided, single submitter clinical testing This sequence change falls in intron 3 of the TNNT2 gene. It does not directly change the encoded amino acid sequence of the TNNT2 protein. This variant is present in population databases (rs764862951, gnomAD 0.0009%). This variant has not been reported in the literature in individuals affected with TNNT2-related conditions. ClinVar contains an entry for this variant (Variation ID: 387466). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. 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.
All of Us Research Program, National Institutes of Health RCV004000470 SCV004830958 uncertain significance Cardiomyopathy 2023-06-26 criteria provided, single submitter clinical testing This variant causes a G to A nucleotide substitution at the -6 position of intron 3 of the TNNT2 gene. Splice site prediction tools are inconclusive regarding the impact of this variant on RNA splicing. To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with TNNT2-related disorders in the literature. This variant has been identified in 1/251208 chromosomes in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance.
