The FLNC c.1102G>A; p.Val368Met variant (rs781718076, ClinVar ID: 471960) is reported in the literature in one proband and father affected with hypertrophic cardiomyopathy (Baban 2022). This variant is found in the general population with an overall allele frequency of 0.005% (13/280,932 alleles) in the Genome Aggregation Database (v2.1.1). Computational analyses predict that this variant is deleterious (REVEL: 0.801). Due to limited information, the clinical significance of this variant is uncertain at this time.

Identified in a proband and father with HCM in published literature; however, it is unclear whether these individuals harbored additional cardiogenetic variants (PMID: 36286284); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; This variant is associated with the following publications: (PMID: 36286284) -

Cardiovascular phenotype Uncertain:1
The p.V368M variant (also known as c.1102G>A), located in coding exon 7 of the FLNC gene, results from a G to A substitution at nucleotide position 1102. The valine at codon 368 is replaced by methionine, an amino acid with highly similar properties. 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. -
