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 Ala630Thr variant in VCL has been identified by our laboratory in 1 adult wi th HCM and VT. It was absent from large population studies. Computational pred iction tools and conservation analysis do not provide strong support for or agai nst an impact to the protein. In summary, the clinical significance of the Ala63 0Thr variant is uncertain. -
