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]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The FLNC c.7499G>A; p.Ser2500Asn variant (rs371244800), to our knowledge, is not reported in the medical literature but is reported in ClinVar (Variation ID: 574790). This variant is found in the African population with an allele frequency of 0.09% (21/24,198 alleles) in the Genome Aggregation Database. Computational analyses are uncertain whether this variant is neutral or deleterious (REVEL: 0.421). Due to limited information, the clinical significance of this variant is uncertain at this time. -

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The p.S2500N variant (also known as c.7499G>A), located in coding exon 45 of the FLNC gene, results from a G to A substitution at nucleotide position 7499. The serine at codon 2500 is replaced by asparagine, an amino acid with highly similar properties. 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. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
