Labcorp Genetics (formerly Invitae), Labcorp RCV001363494 SCV001559609 uncertain significance Primary dilated cardiomyopathy 2021-12-18 criteria provided, single submitter clinical testing This variant is present in population databases (rs531899091, gnomAD 0.003%). 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. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). ClinVar contains an entry for this variant (Variation ID: 1054903). This variant has not been reported in the literature in individuals affected with TXNRD2-related conditions. This sequence change replaces threonine, which is neutral and polar, with methionine, which is neutral and non-polar, at codon 196 of the TXNRD2 protein (p.Thr196Met).
GeneDx RCV001776224 SCV002013022 uncertain significance not provided 2019-06-04 criteria provided, single submitter clinical testing Has not been previously published as pathogenic or benign to our knowledge; Not observed at a significant frequency in large population cohorts (Lek et al., 2016); In silico analysis, which includes protein predictors and evolutionary conservation, supports that this variant does not alter protein structure/function
Ambry Genetics RCV004995712 SCV005521995 uncertain significance Cardiovascular phenotype 2024-11-10 criteria provided, single submitter clinical testing The p.T196M variant (also known as c.587C>T), located in coding exon 7 of the TXNRD2 gene, results from a C to T substitution at nucleotide position 587. The threonine at codon 196 is replaced by methionine, an amino acid with similar properties. This amino acid position is conserved. In addition, this alteration is predicted to be tolerated by in silico analysis. Based on the available evidence, the clinical significance of this variant remains unclear.
