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]

Has not been previously published as pathogenic or benign to our knowledge; Reported in ClinVar as a variant of uncertain significance (ClinVar Variant ID# 539417; Landrum et al., 2016); In silico analysis, which includes protein predictors and evolutionary conservation, supports a deleterious effect -

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The p.G505S variant (also known as c.1513G>A), located in coding exon 9 of the FLNC gene, results from a G to A substitution at nucleotide position 1513. The glycine at codon 505 is replaced by serine, an amino acid with similar properties. This variant was reported in individual(s) with features consistent with dilated cardiomyopathy; however, clinical details were limited, and additional variants in cardiac-related genes were detected (van Lint FHM et al. Neth Heart J, 2019 Jun;27:304-309). This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Based on the available evidence, the clinical significance of this variant remains unclear. -
