Labcorp Genetics (formerly Invitae), Labcorp RCV002543528 SCV001499251 uncertain significance Dyskeratosis congenita, autosomal dominant 2; Idiopathic Pulmonary Fibrosis 2020-05-04 criteria provided, single submitter clinical testing Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. 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. This variant has not been reported in the literature in individuals with TERT-related conditions. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate insufficient coverage at this position in the ExAC database. This sequence change replaces alanine with valine at codon 52 of the TERT protein (p.Ala52Val). The alanine residue is moderately conserved and there is a small physicochemical difference between alanine and valine.
