Invitae RCV000654395 SCV000776288 uncertain significance DICER1-related pleuropulmonary blastoma cancer predisposition syndrome 2017-10-02 criteria provided, single submitter clinical testing This sequence change replaces methionine with isoleucine at codon 324 of the DICER1 protein (p.Met324Ile). The methionine residue is moderately conserved and there is a small physicochemical difference between methionine and isoleucine. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with DICER1-related disease. 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.
