RCV002562559 | SCV001394772 | uncertain significance | Dyskeratosis congenita, autosomal dominant 2; Idiopathic Pulmonary Fibrosis | 2023-11-18 | criteria provided, single submitter | clinical testing | This sequence change replaces alanine, which is neutral and non-polar, with glycine, which is neutral and non-polar, at codon 801 of the TERT protein (p.Ala801Gly). This variant is not present in population databases (gnomAD no frequency). 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: 950854). 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) performed at Invitae indicates that this missense variant is expected to disrupt TERT protein function with a positive predictive value of 95%. 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 | RCV004557442 | SCV002736093 | uncertain significance | Dyskeratosis congenita | 2022-06-03 | criteria provided, single submitter | clinical testing | The p.A801G variant (also known as c.2402C>G), located in coding exon 8 of the TERT gene, results from a C to G substitution at nucleotide position 2402. The alanine at codon 801 is replaced by glycine, 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. |
