Labcorp Genetics (formerly Invitae), Labcorp RCV003103843 SCV000949191 uncertain significance Dyskeratosis congenita, autosomal dominant 2; Idiopathic Pulmonary Fibrosis 2023-10-05 criteria provided, single submitter clinical testing This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 972 of the TERT protein (p.Arg972His). This variant is present in population databases (no rsID available, gnomAD 0.003%). This missense change has been observed in individual(s) with clinical features of autosomal dominant pulmonary fibrosis and/or dyskeratosis congenita (PMID: 21931702, 29749397). ClinVar contains an entry for this variant (Variation ID: 653306). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available". The histidine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. Experimental studies have shown that this missense change affects TERT function (PMID: 28154186). 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.
