Labcorp Genetics (formerly Invitae), Labcorp RCV000635559 SCV000756976 uncertain significance Birt-Hogg-Dube syndrome 2024-02-11 criteria provided, single submitter clinical testing This sequence change replaces serine, which is neutral and polar, with glycine, which is neutral and non-polar, at codon 68 of the FLCN protein (p.Ser68Gly). This variant is present in population databases (rs587778365, gnomAD 0.003%). 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: 134422). 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 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.
Ambry Genetics RCV004019682 SCV005030808 uncertain significance Hereditary cancer-predisposing syndrome 2023-11-21 criteria provided, single submitter clinical testing The p.S68G variant (also known as c.202A>G), located in coding exon 1 of the FLCN gene, results from an A to G substitution at nucleotide position 202. The serine at codon 68 is replaced by glycine, an amino acid with 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.
