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.R1494W variant (also known as c.4480C>T), located in coding exon 26 of the FLNC gene, results from a C to T substitution at nucleotide position 4480. The arginine at codon 1494 is replaced by tryptophan, an amino acid with dissimilar properties. This variant has been detected in an individual with unspecified cardiomyopathy, and individual with hyperCKemia, and an individual with features of arrhythmogenic right ventricular cardiomyopathy (Kodali M et al. JACC Case Rep, 2024 Feb;29:102198; Çavdarl B et al. Ann Hum Genet, 2023 May;87:104-114; Akinrinade O et al. J Cardiovasc Transl Res, 2023 Dec;16:1287-1302). This amino acid position is not well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Based on the available evidence, the clinical significance of this variant remains unclear. -
