RCV002554516 | SCV001232379 | uncertain significance | Dyskeratosis congenita, autosomal dominant 2; Idiopathic Pulmonary Fibrosis | 2023-10-25 | criteria provided, single submitter | clinical testing | This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 198 of the TERT protein (p.Gly198Arg). This variant is present in population databases (rs758442518, gnomAD 0.03%). 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: 860925). 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 not expected to disrupt TERT protein function with a negative predictive value of 80%. 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 | RCV004559894 | SCV005048957 | uncertain significance | Dyskeratosis congenita | 2023-03-25 | criteria provided, single submitter | clinical testing | The p.G198R variant (also known as c.592G>A), located in coding exon 2 of the TERT gene, results from a G to A substitution at nucleotide position 592. The glycine at codon 198 is replaced by arginine, an amino acid with dissimilar properties. This amino acid position is conserved. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |
