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]

Nov 24, 2022

ClinVar contains an entry for this variant (Variation ID: 472120). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. This missense change has been observed in individual(s) with clinical features of FLNC-related conditions (Invitae). This variant is present in population databases (no rsID available, gnomAD 0.002%). This sequence change replaces glutamic acid, which is acidic and polar, with alanine, which is neutral and non-polar, at codon 20 of the FLNC protein (p.Glu20Ala). -
