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]

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. This sequence change replaces proline, which is neutral and non-polar, with alanine, which is neutral and non-polar, at codon 2 of the VCL protein (p.Pro2Ala). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with VCL-related conditions. ClinVar contains an entry for this variant (Variation ID: 2056170). 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. -
