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

Verdict is Likely_benign. Variant got -5 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.14).
• BS2: High AC in GnomAdExome4 at 8 AD gene.

Collection Method: clinical testing

The c.-4C>T variant is located in the 5' untranslated region (5’UTR) of the VCL gene. This variant results from a C to T substitution 4 nucleotides upstream from the first translated codon. This nucleotide position is highly conserved in available vertebrate species. The evidence for this gene-disease relationship is limited; therefore, the clinical significance of this alteration is unclear. -
