RCV003807652 | SCV004605613 | uncertain significance | Dyskeratosis congenita, autosomal dominant 2; Idiopathic Pulmonary Fibrosis | 2023-07-25 | criteria provided, single submitter | clinical testing | 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. 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. This variant has not been reported in the literature in individuals affected with TERT-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces arginine, which is basic and polar, with glycine, which is neutral and non-polar, at codon 972 of the TERT protein (p.Arg972Gly). |
| Ambry Genetics | RCV004559020 | SCV005049189 | uncertain significance | Dyskeratosis congenita | 2023-09-24 | criteria provided, single submitter | clinical testing | The p.R972G variant (also known as c.2914C>G), located in coding exon 12 of the TERT gene, results from a C to G substitution at nucleotide position 2914. The arginine at codon 972 is replaced by glycine, an amino acid with dissimilar 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. |
