Invitae RCV001238307 SCV001411110 uncertain significance DICER1-related tumor predisposition 2023-03-24 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. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt DICER1 protein function. ClinVar contains an entry for this variant (Variation ID: 964142). This variant has not been reported in the literature in individuals affected with DICER1-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces histidine, which is basic and polar, with arginine, which is basic and polar, at codon 856 of the DICER1 protein (p.His856Arg).
Ambry Genetics RCV002430018 SCV002744445 uncertain significance Hereditary cancer-predisposing syndrome 2022-04-24 criteria provided, single submitter clinical testing The p.H856R variant (also known as c.2567A>G), located in coding exon 15 of the DICER1 gene, results from an A to G substitution at nucleotide position 2567. The histidine at codon 856 is replaced by arginine, an amino acid with highly similar properties. This amino acid position is conserved. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
