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.A1569T variant (also known as c.4705G>A), located in coding exon 27 of the FLNC gene, results from a G to A substitution at nucleotide position 4705. The alanine at codon 1569 is replaced by threonine, an amino acid with similar properties. This variant co-occurred with variants in other genes in a case from a limb-girdle muscular dystrophy cohort (Fichna JP et al. Hum Genomics, 2018 Jul;12:34). This amino acid position is highly 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. -
