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]

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The p.P1031L variant (also known as c.3092C>T), located in coding exon 20 of the FLNC gene, results from a C to T substitution at nucleotide position 3092. The proline at codon 1031 is replaced by leucine, an amino acid with similar properties. This variant has been detected in an individual from a hypertrophic cardiomyopathy cohort, and in unaffected relatives (Gómez J et al. Circ Cardiovasc Genet, 2017 Apr;10). This amino acid position is well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
