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]

Uncertain significance, no assertion criteria provided	provider interpretation	Stanford Center for Inherited Cardiovascular Disease, Stanford University	Sep 11, 2017	c.7560C>T (silent, splice region) in exon 45 of the FLNC gene (NM_001458.4; chr7-128496974-C-T) SCICD classification: variant of uncertain significance based on lack of case data. However, this variant is relatively prevalent in some ethnic populations. We do not feel it is suitable for assessing risk in healthy relatives ("predictive genetic testing"). Gene-level evidence: Both missense and truncating variants in FLNC have been reported in various cardiomyopathies (Ortiz-Genga et al. 2016; Valdes-Mas et al 2014). Variant type: Missense. Case data: Â· ClinVar: not present Â· Cases in the literature: none reported Functional data: none reported. In silico models (for missense variants only): not applicable Splicing algorithms: Per the test report, "Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant is not likely to affect RNA splicing, but this prediction has not been confirmed by published transcriptional studies." Conservation data: The thymine at position 7560 in the cDNA is completely conserved across species, as are neighboring nucleotides. Other variants associated with disease at this nucleotide: none Population data: MAF=0.02% in East Asians: Â· The variant was reported online in 8 of 137,599 individuals in the Genome Aggregation Consortium Dataset (gnomAD; http://gnomad.broadinstitute.org/), which currently includes variant calls on >140,000 unrelated individuals of African, Asian, European, Ashkenazi, Latino descent. Specifically, the variant was observed in 4 of 9,414 individuals of East Asian descent (MAF=0.02%), 3 of 15,367 individuals of South Asian descent and 1 of 62,589 individuals of European descent. The phenotype of those individuals is not publicly available. The dataset is comprised of multiple cohorts, some of which were recruited from the general population, others were enriched for common cardiovascular disease. -

This sequence change affects codon 2520 of the FLNC mRNA. It is a 'silent' change, meaning that it does not change the encoded amino acid sequence of the FLNC protein. It affects a nucleotide within the consensus splice site. This variant is present in population databases (rs527921534, gnomAD 0.02%). This variant has been observed in individual(s) with hypertrophic cardiomyopathy (Invitae). ClinVar contains an entry for this variant (Variation ID: 472177). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant is not likely to affect RNA splicing. 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. -

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
