Labcorp Genetics (formerly Invitae), Labcorp RCV002592646 SCV002279206 uncertain significance Dyskeratosis congenita, autosomal dominant 2; Idiopathic Pulmonary Fibrosis 2021-03-25 criteria provided, single submitter clinical testing This variant has not been reported in the literature in individuals with TERT-related conditions. 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 not expected to disrupt TERT protein function. This variant is not present in population databases (ExAC no frequency). This sequence change replaces glutamine with lysine at codon 340 of the TERT protein (p.Gln340Lys). The glutamine residue is weakly conserved and there is a small physicochemical difference between glutamine and lysine.
