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 FLNC c.2075T>C; p.Ile692Thr variant (rs538863259), to our knowledge, is not reported in the medical literature but is reported in ClinVar (Variation ID: 583051). This variant is found in the general population with an overall allele frequency of 0.003% (9/280,974 alleles) in the Genome Aggregation Database (v2.1.1). Computational analyses predict that this variant is deleterious (REVEL: 0.796). Due to limited information, the clinical significance of this variant is uncertain at this time. -

Collection Method: clinical testing

The p.I692T variant (also known as c.2075T>C), located in coding exon 13 of the FLNC gene, results from a T to C substitution at nucleotide position 2075. The isoleucine at codon 692 is replaced by threonine, an amino acid with similar properties. This amino acid position is conserved. 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. -
