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 c.622+4C>G variant in VCL has not been previously reported in individuals wi th cardiomyopathy, but has been identified in 5/66734 European chromosomes by th e Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs20 1020802). This variant is located in the 5' splice region. Computational tools d o not suggest an impact to splicing, though this information is not predictive e nough to rule out pathogenicity. In summary, the clinical significance of the c. 622+4C>G variant is uncertain. -

This sequence change falls in intron 5 of the VCL gene. It does not directly change the encoded amino acid sequence of the VCL protein. It affects a nucleotide within the consensus splice site. This variant is present in population databases (rs201020802, gnomAD 0.009%). This variant has not been reported in the literature in individuals affected with VCL-related conditions. ClinVar contains an entry for this variant (Variation ID: 229632). Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant is not likely to affect RNA splicing. 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. -

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.622+4C>G intronic variant results from a C to G substitution 4 nucleotides after coding exon 5 in the VCL gene. This nucleotide position is poorly conserved in available vertebrate species. In silico splice site analysis predicts that this alteration will not have any significant effect on splicing. The evidence for this gene-disease relationship is limited; therefore, the clinical significance of this alteration is unclear. -
