DICER1-related tumor predisposition Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | May 11, 2020 | 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. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with DICER1-related conditions. This variant is present in population databases (rs771634025, ExAC 0.003%). This sequence change replaces leucine with tryptophan at codon 616 of the DICER1 protein (p.Leu616Trp). The leucine residue is highly conserved and there is a small physicochemical difference between leucine and tryptophan. - |
