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 Ser600Arg variant in the VCL gene has not been reported as a disease-causing mutation or as a benign polymorphism to our knowledge. Ser600Arg results in a semi-conservative amino acid substitution of a neutral, polar Serine to a positively-charged Arginine at a position that is highly conserved across species. In silico analysis predicts Ser600Arg is damaging to the protein structure/function. The Ser600Arg variant was not observed in approximately 6500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. However, very few missense mutations in the VCL gene have been reported, and none of these reported mutations are near Ser600Arg, indicating this region of the protein may tolerate change.With the clinical and molecular information available at this time, we cannot definitively determine if Ser600Arg is a disease-causing mutation or a rare benign variant. The variant is found in DCM panel(s). -

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. 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. ClinVar contains an entry for this variant (Variation ID: 45591). This missense change has been observed in individual(s) with clinical features of left ventricular noncompaction (PMID: 33500567). This variant is present in population databases (rs397517236, gnomAD 0.007%). This sequence change replaces serine, which is neutral and polar, with arginine, which is basic and polar, at codon 600 of the VCL protein (p.Ser600Arg). -
