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]

Variant classified as Uncertain Significance - Favor Pathogenic. The p.Arg105X v ariant in VCL has not been identified in individuals with cardiomyopathy, but ha s been identified in 3/246076 total chromosomes by the Genome Aggregation Databa se (gnomAD, http://gnomad.broadinstitute.org; dbSNP rs397517239). This nonsense variant leads to a premature termination codon at position 105, which is predict ed to lead to a truncated or absent protein. Animal models have shown that loss of function (LOF) of the VCL gene can impact cardiac function resulting in pheno types ranging from arrhythmia to cardiomyopathy (Zemljic-Harpf 2004; Zemljic-Har pf 2007). In summary, while there is some suspicion that LOF variants may contri bute to cardiomyopathy, the clinical significance of the p.Arg105X variant is un certain.

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. The current clinical and genetic evidence is not sufficient to establish whether loss-of-function variants in VCL cause disease. This variant has been observed in individual(s) with dilated cardiomyopathy (PMID: 24503780). ClinVar contains an entry for this variant (Variation ID: 45606). This variant is present in population databases (rs397517239, ExAC 0.001%). This sequence change creates a premature translational stop signal (p.Arg105*) in the VCL gene. It is expected to result in an absent or disrupted protein product. -
