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 p.Gly400Cys variant in VCL has been identified in 1 individual with HCM (LMM data) and 0.02% (6/30616) of South Asian chromosomes by gnomAD (https://gnomad.broadinstitute.org). This variant has also been reported in ClinVar (Variation ID 166542). Computational prediction tools and conservation analysis do not provide strong support for or against an impact to the protein. In summary, the clinical significance of this variant is uncertain. ACMG/AMP Criteria applied: BS1_Supporting. -

Has not been previously published as pathogenic or benign to our knowledge; Reported in ClinVar but additional evidence is not available (ClinVar Variant ID# 166542; Landrum et al., 2016); In silico analysis, which includes protein predictors and evolutionary conservation, supports that this variant does not alter protein structure/function -

The p.G400C variant (also known as c.1198G>T), located in coding exon 10 of the VCL gene, results from a G to T substitution at nucleotide position 1198. The glycine at codon 400 is replaced by cysteine, an amino acid with highly dissimilar properties. This alteration has been reported as a secondary cardiac variant in an exome cohort; however, clinical details are limited (Ng D et al. Circ Cardiovasc Genet, 2013 Aug;6:337-46). This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
