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]

ACMG classification

Our verdict: Pathogenic. The variant received 11 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 10-74097222-C-T is Pathogenic according to our data. Variant chr10-74097222-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 177889.

Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine

Significance: Likely pathogenic

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The Gln588X variant has not been reported in the literature. This variant leads to a premature stop at codon 588. This alteration is predicted to lead to a trun cated or completely absent protein (loss of function). Although the VCL gene has not yet been implicated in the etiology of LVNC and the variant spectrum is not yet well defined, our laboratory has identified loss of function variants in VC L in 4/14 probands with DCM and/or LVNC. Furthermore, mouse models have shown th at loss of function of the VCL gene can lead to DCM. In summary, the Gln588X va riant is likely to be pathogenic.
