Invitae | RCV000538026 | SCV000623492 | uncertain significance | Primary dilated cardiomyopathy | 2024-01-22 | criteria provided, single submitter | clinical testing | This sequence change replaces serine, which is neutral and polar, with cysteine, which is neutral and slightly polar, at codon 74 of the TXNRD2 protein (p.Ser74Cys). This variant is present in population databases (rs200942544, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with TXNRD2-related conditions. ClinVar contains an entry for this variant (Variation ID: 454284). 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. 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. |

Ambry Genetics | RCV002431507 | SCV002729670 | uncertain significance | Cardiovascular phenotype | 2023-06-05 | criteria provided, single submitter | clinical testing | The p.S74C variant (also known as c.221C>G), located in coding exon 3 of the TXNRD2 gene, results from a C to G substitution at nucleotide position 221. The serine at codon 74 is replaced by cysteine, an amino acid with dissimilar properties. This amino acid position is well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. The evidence for this gene-disease relationship is limited; therefore, the clinical significance of this alteration is unclear. |
