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]

The FLNC c.1102G>A; p.Val368Met variant (rs781718076, ClinVar ID: 471960) is reported in the literature in one proband and father affected with hypertrophic cardiomyopathy (Baban 2022). This variant is found in the general population with an overall allele frequency of 0.005% (13/280,932 alleles) in the Genome Aggregation Database (v2.1.1). Computational analyses predict that this variant is deleterious (REVEL: 0.801). Due to limited information, the clinical significance of this variant is uncertain at this time.

The p.V368M variant (also known as c.1102G>A), located in coding exon 7 of the FLNC gene, results from a G to A substitution at nucleotide position 1102. The valine at codon 368 is replaced by methionine, 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. -
