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]

This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 975 of the VCL protein (p.Arg975Trp). This variant is present in population databases (rs121917776, gnomAD 0.03%). This missense change has been observed in individual(s) with hypertrophic cardiomyopathy (HCM) and dilated cardiomyopathy (DCM) (PMID: 11815424, 17097056). ClinVar contains an entry for this variant (Variation ID: 12197). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. Experimental studies have shown that this missense change affects VCL function (PMID: 23159629, 27503891). 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 p.R975W variant (also known as c.2923C>T), located in coding exon 19 of the VCL gene, results from a C to T substitution at nucleotide position 2923. The arginine at codon 975 is replaced by tryptophan, an amino acid with dissimilar properties. This amino acid position is well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. The evidence for this gene-disease relationship is limited; therefore, the clinical significance of this alteration is unclear. -
