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 Benign. Variant got -16 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.84).
• BP6: Variant 10-74090008-C-T is Benign according to our data. Variant chr10-74090008-C-T is described in ClinVar as [Benign]. Clinvar id is 45574.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr10-74090008-C-T is described in Lovd as [Benign]. Variant chr10-74090008-C-T is described in Lovd as [Likely_benign].
• BS2: High AC in GnomAd4 at 567 AD gene.

Variant summary: VCL c.1177-15C>T alters a non-conserved nucleotide located close to a canonical splice site and therefore could affect mRNA splicing, leading to a significantly altered protein sequence. 4/4 computational tools predict no significant impact on normal splicing. However, these predictions have yet to be confirmed by functional studies. The variant allele was found at a frequency of 0.0013 in 282754 control chromosomes, predominantly at a frequency of 0.013 within the African or African-American subpopulation in the gnomAD database, including 1 homozygote. The observed variant frequency within African or African-American control individuals in the gnomAD database is approximately 520 fold of the estimated maximal expected allele frequency for a pathogenic variant in VCL causing Cardiomyopathy phenotype (2.5e-05), strongly suggesting that the variant is a benign polymorphism found primarily in populations of African or African-American origin. To our knowledge, no occurrence of c.1177-15C>T in individuals affected with Cardiomyopathy and no experimental evidence demonstrating its impact on protein function have been reported. One ClinVar submitter (evaluation after 2014) cites the variant as benign. Based on the evidence outlined above, the variant was classified as benign. -

Significance: Benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. -
