Invitae | RCV001349162 | SCV001543491 | uncertain significance | Birt-Hogg-Dube syndrome | 2024-01-19 | criteria provided, single submitter | clinical testing | This sequence change replaces lysine, which is basic and polar, with arginine, which is basic and polar, at codon 516 of the FLCN protein (p.Lys516Arg). This variant is not present in population databases (gnomAD no frequency). 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: 1044847). 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. |

In the absence of RNA/functional studies, the actual effect of this sequence change is unknown.; This variant is associated with the following publications: (PMID: 17028174) |
Ambry Genetics | RCV002404827 | SCV002709328 | uncertain significance | Hereditary cancer-predisposing syndrome | 2021-03-22 | criteria provided, single submitter | clinical testing | The p.K516R variant (also known as c.1547A>G), located in coding exon 11 of the FLCN gene, results from an A to G substitution at nucleotide position 1547. The lysine at codon 516 is replaced by arginine, an amino acid with highly similar properties. This amino acid position is highly 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. |
