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]

Variant summary: FLNC c.1757T>C (p.Val586Ala) results in a non-conservative amino acid change in the encoded protein sequence. Four of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 3.3e-05 in 241768 control chromosomes. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. c.1757T>C has been reported in the literature in individual(s) affected with Dilated Cardiomyopathy (Begay_2018). These report(s) do not provide unequivocal conclusions about association of the variant with Dilated Cardiomyopathy. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publication have been ascertained in the context of this evaluation (PMID: 30067491). ClinVar contains an entry for this variant (Variation ID: 471987). Based on the evidence outlined above, the variant was classified as uncertain significance. -

Collection Method:clinical testing

The p.V586A variant (also known as c.1757T>C), located in coding exon 11 of the FLNC gene, results from a T to C substitution at nucleotide position 1757. The valine at codon 586 is replaced by alanine, an amino acid with similar properties. This alteration has been reported in a dilated cardiomyopathy (DCM) cohort (Begay RL et al. JACC Clin Electrophysiol, 2018 Apr;4:504-514). 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. -
