Genes affected

VCL (HGNC:12665): (vinculin) Vinculin is a cytoskeletal protein associated with cell-cell and cell-matrix junctions, where it is thought to function as one of several interacting proteins involved in anchoring F-actin to the membrane. Defects in VCL are the cause of cardiomyopathy dilated type 1W. Dilated cardiomyopathy is a disorder characterized by ventricular dilation and impaired systolic function, resulting in congestive heart failure and arrhythmia. Multiple alternatively spliced transcript variants have been found for this gene, but the biological validity of some variants has not been determined. [provided by RefSeq, Jul 2008]

The VCL c.1621C>G; p.Leu541Val variant (rs370229150) is reported in the literature in a cohort of individuals affected with hypertrophic cardiomyopathy (Lopes 2015). This variant is reported in ClinVar (Variation ID: 263345) and is found in the non-Finnish European population with an overall allele frequency of 0.01% (17/126714 alleles) in the Genome Aggregation Database. The leucine at codon 541 is highly conserved, but computational analyses (SIFT, PolyPhen-2) predict that this variant is tolerated. However, given the lack of clinical and functional data, the significance of the p.Leu541Val variant is uncertain at this time. References: Lopes LR et al. Novel genotype-phenotype associations demonstrated by high-throughput sequencing in patients with hypertrophic cardiomyopathy. Heart. 2015 Feb;101(4):294-301. -

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This sequence change replaces leucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 541 of the VCL protein (p.Leu541Val). This variant is present in population databases (rs370229150, gnomAD 0.01%). This missense change has been observed in individual(s) with hypertrophic cardiomyopathy (HCM) (PMID: 25351510). ClinVar contains an entry for this variant (Variation ID: 263345). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant¬†is likely to be tolerated. 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. -

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The p.L541V variant (also known as c.1621C>G), located in coding exon 12 of the VCL gene, results from a C to G substitution at nucleotide position 1621. The leucine at codon 541 is replaced by valine, an amino acid with highly similar properties. This variant has been detected in a hypertrophic cardiomyopathy cohort; however, clinical details were limited (Lopes LR et al. Heart. 2015;101(4):294-301). 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. -
