Labcorp Genetics (formerly Invitae), Labcorp RCV000699923 SCV000828654 uncertain significance DICER1-related tumor predisposition 2020-03-05 criteria provided, single submitter clinical testing 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 do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with DICER1-related disease. This variant is not present in population databases (ExAC no frequency). This sequence change replaces serine with phenylalanine at codon 1286 of the DICER1 protein (p.Ser1286Phe). The serine residue is highly conserved and there is a large physicochemical difference between serine and phenylalanine.
Ambry Genetics RCV002352182 SCV002621527 uncertain significance Hereditary cancer-predisposing syndrome 2021-12-30 criteria provided, single submitter clinical testing The p.S1286F variant (also known as c.3857C>T), located in coding exon 20 of the DICER1 gene, results from a C to T substitution at nucleotide position 3857. The serine at codon 1286 is replaced by phenylalanine, an amino acid with highly dissimilar properties. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
