RCV002547095 | SCV000813764 | uncertain significance | Dyskeratosis congenita, autosomal dominant 2; Idiopathic Pulmonary Fibrosis | 2023-09-08 | criteria provided, single submitter | clinical testing | This sequence change replaces threonine, which is neutral and polar, with methionine, which is neutral and non-polar, at codon 319 of the TERT protein (p.Thr319Met). This variant is present in population databases (no rsID available, gnomAD 0.001%). This variant has not been reported in the literature in individuals affected with TERT-related conditions. ClinVar contains an entry for this variant (Variation ID: 566445). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on TERT protein function. 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 | RCV004559350 | SCV002690784 | uncertain significance | Dyskeratosis congenita | 2022-02-10 | criteria provided, single submitter | clinical testing | The p.T319M variant (also known as c.956C>T), located in coding exon 2 of the TERT gene, results from a C to T substitution at nucleotide position 956. The threonine at codon 319 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. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |
