Invitae RCV000560280 SCV000658190 uncertain significance DICER1-related pleuropulmonary blastoma cancer predisposition syndrome 2018-12-24 criteria provided, single submitter clinical testing This sequence change replaces isoleucine with valine at codon 846 of the DICER1 protein (p.Ile846Val). The isoleucine residue is highly conserved and there is a small physicochemical difference between isoleucine and valine. This variant is present in population databases (rs201212908, ExAC 0.009%). This variant has not been reported in the literature in individuals with DICER1-related disease. ClinVar contains an entry for this variant (Variation ID: 477106). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The valine amino acid residue is found in multiple mammalian species, suggesting that this missense change does not adversely affect protein function. 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.
