Variant summary
Our verdict is Likely benign. Variant got -6 ACMG points: 0P and 6B. BP4_ModerateBS2
The NM_144997.7(FLCN):c.175C>T(p.Arg59Cys) variant causes a missense change. The variant allele was found at a frequency of 0.0000217 in 1,614,026 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 12/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R59H) has been classified as Uncertain significance.

Uncertain significance, criteria provided, single submitter | clinical testing | GeneDx | Apr 12, 2023 | In silico analysis supports that this missense variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge; This variant is associated with the following publications: (PMID: 30709382) - |
Birt-Hogg-Dube syndrome Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Jan 19, 2024 | This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 59 of the FLCN protein (p.Arg59Cys). This variant is present in population databases (rs778275358, gnomAD 0.01%). 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: 529978). 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. - |
Hereditary cancer-predisposing syndrome Benign:1
Benign, criteria provided, single submitter | clinical testing | Ambry Genetics | Mar 28, 2023 | This alteration is classified as benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. - |
