Variant summary

Our verdict is Likely benign. The variant received -3 ACMG points: 1P and 4B. PP3BS2

The NM_014000.3(VCL):​c.1559G>A​(p.Arg520Gln) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000157 in 1,461,646 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R520W) has been classified as Uncertain significance.

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]

Sudden unexplained death Uncertain:1
Mar 17, 2017
Agnes Ginges Centre for Molecular Cardiology, Centenary Institute
Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:research

The VCL Arg520Gln is absent in the large Exome Aggregation Consortium dataset (http://exac.broadinstitute.org/). Arginine (Arg) at position 520 is highly conserved across distantly related species, and computational prediction tools are supportive of a deleterious effect (SIFT "deleterious"; PolyPhen-2 "probably damaging"; MutationTaster "disease-causing"). We have identified this variant in 1 patient who had an unexplained resuscitated cardiac arrest event. The patient has no family history of a genetic heart condition or sudden cardiac death. Based on limited available information and rarity in the general population, we classify VCL Arg520Gln as a variant of "uncertain significance". -

Dilated cardiomyopathy 1W Uncertain:1
Oct 03, 2022
Labcorp Genetics (formerly Invitae), Labcorp
Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 520 of the VCL protein (p.Arg520Gln). This variant is present in population databases (rs757009736, gnomAD 0.006%). This missense change has been observed in individual(s) with hypertrophic cardiomyopathy (Invitae). ClinVar contains an entry for this variant (Variation ID: 222888). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Not Available"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Not Available"). 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. -
