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 lysine, which is basic and polar, with arginine, which is basic and polar, at codon 815 of the VCL protein (p.Lys815Arg). This variant is present in population databases (rs373010557, gnomAD 0.01%). This missense change has been observed in individual(s) with clinical features of dilated cardiomyopathy (PMID: 24062880, 27532257, 30847666, 32880476). ClinVar contains an entry for this variant (Variation ID: 45596). 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. 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 Lys815Arg variant in VCL has been identified in one individual with DCM who also carried a second variant of unknown significance in MYBPC3 and segregated w ith disease in 3 affected family members, 2 of whom also carried the MYBPC3 vari ant (Wells 2011 and LMM unpublished data). The Lys815Arg variant has been identi fied in 1/8600 European American chromosomes by the NHLBI Exome Sequencing Proje ct (http://evs.gs.washington.edu/EVS; dbSNP rs373010557). Lysine (Lys) at positi on 815 is highly conserved in mammals and evolutionarily distant species, sugges ting that a change at this position may not be tolerated. While VCL variants ha ve been identified in individuals with HCM as well as DCM (Olson 2002, Vasile 20 06), few studies exist and the contribution of VCL to HCM and/or DCM as well as the types of pathogenic variation have not been well established. In summary, th e clinical significance of the Lys815Arg variant is uncertain and additional stu dies are needed to fully establish its clinical significance. -

Reported with an MYBPC3 variant in a proband with DCM and a family history of DCM and bicuspid aortic valve; three affected relatives harbored the VCL variant, two of whom also harbored the MYBPC3 variant (Wells et al., 2011); In silico analysis supports that this missense variant does not alter protein structure/function; This variant is associated with the following publications: (PMID: 27532257, 24503780, 24062880, 32880476, 30847666) -

The c.2444A>G (p.K815R) alteration is located in exon 17 (coding exon 17) of the VCL gene. This alteration results from a A to G substitution at nucleotide position 2444, causing the lysine (K) at amino acid position 815 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
