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 p.R1931C variant (also known as c.5791C>T), located in coding exon 35 of the FLNC gene, results from a C to T substitution at nucleotide position 5791. The arginine at codon 1931 is replaced by cysteine, an amino acid with highly dissimilar properties. This variant has been detected in control cohorts; however, clinical details were limited (Janssens J et al. Acta Neuropathol Commun. 2015 Nov;3:68; Cui H et al. Mol Genet Genomic Med, 2018 11;6:1104-1113). This variant has also been seen in dilated cardiomyopathy cohorts; however, details were limited and, in one case, it co-occurred with a variant in another cardiac-related gene (Herkert JC et al. Genet. Med., 2018 11;20:1374-1386;Verdonschot JAJ et al. Hum Mutat. 2020 06;41(6):1091-1111; Lian H et al. J Transl Med, 2023 Jul;21:476). This amino acid position is not well 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.
