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 Leu682Phe variant in VCL has not been previously reported in individuals wit h cardiomyopathy or in large population studies. Computational prediction tools and conservation analysis do not provide strong support for or against an impact to the protein. Additional information is needed to fully assess the clinical s ignificance of the variant. -

This sequence change replaces leucine, which is neutral and non-polar, with phenylalanine, which is neutral and non-polar, at codon 682 of the VCL protein (p.Leu682Phe). This variant is present in population databases (rs565398652, gnomAD 0.01%). This missense change has been observed in individual(s) with VCL-related conditions (PMID: 27930701, 30847666, 33012304). ClinVar contains an entry for this variant (Variation ID: 166551). 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 disruptive. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. 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. -

Identified in patients with cardiomyopathy and sudden cardiac death; however, several of these patients also harbor additional variants (PMID: 27930701, 30847666, 33012304, 31970460); At the protein level, in silico analysis supports that this missense variant does not alter protein structure/function; At the mRNA level, 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: 30847666, 33012304, 31970460, 27930701) -

The p.L682F variant (also known as c.2046A>T), located in coding exon 15 of the VCL gene, results from an A to T substitution at nucleotide position 2046. The leucine at codon 682 is replaced by phenylalanine, an amino acid with highly similar properties. This variant has been reported in individuals with dilated cardiomyopathy (DCM) and hypertrophic cardiomyopathy (HCM), including individuals from cardiomyopathy, sudden death, and genetic testing cohorts; however, clinical details were limited, and additional cardiac variants were detected in some cases (Sanchez O et al. PLoS One, 2016 Dec;11:e0167358; Mademont-Soler I et al. PLoS One, 2017 Aug;12:e0181465; Robyns T et al. Eur J Hum Genet, 2017 12;25:1313-1323; van Lint FHM et al. Neth Heart J, 2019 Jun;27:304-309). 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. -
