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.A1588G variant (also known as c.4763C>G), located in coding exon 28 of the FLNC gene, results from a C to G substitution at nucleotide position 4763. The alanine at codon 1588 is replaced by glycine, an amino acid with similar properties. This alteration has been reported in an autism spectrum disease cohort that underwent exome sequencing (Ji X et al. Proc Natl Acad Sci U S A, 2016 Dec;113:15054-15059). 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. -
