Ambry Genetics RCV001010524 SCV001170740 uncertain significance Hereditary cancer-predisposing syndrome 2024-06-15 criteria provided, single submitter clinical testing The p.R414Q variant (also known as c.1241G>A), located in coding exon 8 of the FLCN gene, results from a G to A substitution at nucleotide position 1241. The arginine at codon 414 is replaced by glutamine, an amino acid with highly similar properties. This amino acid position is well conserved in available vertebrate species. 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.
Labcorp Genetics (formerly Invitae), Labcorp RCV001059187 SCV001223801 uncertain significance Birt-Hogg-Dube syndrome 2024-09-22 criteria provided, single submitter clinical testing This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 414 of the FLCN protein (p.Arg414Gln). This variant is present in population databases (no rsID available, gnomAD 0.005%). This variant has not been reported in the literature in individuals affected with FLCN-related conditions. ClinVar contains an entry for this variant (Variation ID: 818689). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt FLCN protein function with a negative predictive value of 80%. 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.
GeneDx RCV001766826 SCV002008226 uncertain significance not provided 2019-10-10 criteria provided, single submitter clinical testing In silico analysis, which includes protein predictors and evolutionary conservation, supports that this variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge
