Genes affected
FLNC (HGNC:3756): (filamin C) This gene encodes one of three related filamin genes, specifically gamma filamin. These filamin proteins crosslink actin filaments into orthogonal networks in cortical cytoplasm and participate in the anchoring of membrane proteins for the actin cytoskeleton. Three functional domains exist in filamin: an N-terminal filamentous actin-binding domain, a C-terminal self-association domain, and a membrane glycoprotein-binding domain. Mutations in this gene are a cause of cardiopathy. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, May 2022]

Cardiovascular phenotype Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 13, 2024The p.P1711L variant (also known as c.5132C>T), located in coding exon 30 of the FLNC gene, results from a C to T substitution at nucleotide position 5132. The proline at codon 1711 is replaced by leucine, an amino acid with similar properties. This variant was reported in a hypertrophic cardiomyopathy cohort; however, clinical details were limited (Cui H et al. Mol Genet Genomic Med, 2018 11;6:1104-1113). This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -

Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpOct 22, 2023This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 1711 of the FLNC protein (p.Pro1711Leu). This variant is present in population databases (rs748879903, gnomAD 0.002%). This missense change has been observed in individual(s) with hypertrophic cardiomyopathy (PMID: 30411535). ClinVar contains an entry for this variant (Variation ID: 569395). 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) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on FLNC protein function. 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. -
