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]

ACMG classification

Verdict is Likely_benign. Variant got -6 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.21065542).
• BS2: High AC in GnomAdExome4 at 8 AD gene.

VCL Ser11Asn c.32G>A, exon 1 (NM_014000.2, hg19 chr10-75757997-G-A) SCICD Classification: We do not feel it is suitable for assessing risk in healthy relatives ("predictive genetic testing"). The rationale for this assessment is: lack of gene-level evidence, lack of case data, frequency of the variant in an ethnicity-matched population. We have seen this variant in a person with HCM. Gene-level evidence: There is limited gene-level evidence linking this gene to HCM. Case data (does not include this patient): none (10/5/2017). Cases in the literature: none reported. Segregation data: none reported. Functional data: none. In silico data (missense variants only): Per the test report, "Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0")." Conservation data: The serine at codon 11 is conserved across all aligned vertebrates in the UCSC browser. Neighboring amino acids are conserved. Nearby pathogenic variants at this codon or neighboring codons: Another variant affecting the same codon (Ser11Gly, c.31A>G) was listed in ClinVar as a variant of uncertain significance by LMM. No case data provided. Population data: Highest MAF in East Asian population: 0.06%. The variant was reported online in 10 of 120,993 individuals (MAF: 0.004%) in the Genome Aggregation Consortium Dataset (gnomAD; http://gnomad.broadinstitute.org/), which currently includes variant calls on >140,000 unrelated individuals of African, Asian, European, Ashkenazi, Latino descent. Specifically, the variant was observed in 10 of 8,548 individuals of East Asian descent (MAF=0.06%). The phenotype of those individuals is not publicly available. The dataset is comprised of multiple cohorts, some of which were recruited from the general population, others were enriched for common cardiovascular disease. -

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The p.S11N variant (also known as c.32G>A), located in coding exon 1 of the VCL gene, results from a G to A substitution at nucleotide position 32. The serine at codon 11 is replaced by asparagine, an amino acid with highly similar properties. This amino acid position is conserved. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
