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 -20 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.87).
• BP6: Variant 10-74082557-T-C is Benign according to our data. Variant chr10-74082557-T-C is described in ClinVar as [Likely_benign]. Clinvar id is 517310.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr10-74082557-T-C is described in Lovd as [Likely_benign].
• BS1: Variant frequency is greater than expected in population mid. gnomad4_exome allele frequency = 0.0000349 (51/1460944) while in subpopulation MID AF= 0.0033 (19/5764). AF 95% confidence interval is 0.00216. There are 1 homozygotes in gnomad4_exome. There are 27 alleles in male gnomad4_exome subpopulation. Median coverage is 31. This position pass quality control queck.
• BS2: High AC in GnomAd at 7 AD gene.

Benign, criteria provided, single submitter	clinical testing	Women's Health and Genetics/Laboratory Corporation of America, LabCorp	May 10, 2021	Variant summary: VCL c.874+13T>C 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 4e-05 in 251016 control chromosomes. The observed variant frequency is slightly higher than the estimated maximal expected allele frequency for a pathogenic variant in VCL causing Cardiomyopathy phenotype (2.5e-05), suggesting that the variant may be benign. To our knowledge, no occurrence of c.874+13T>C in individuals affected with Cardiomyopathy and no experimental evidence demonstrating its impact on protein function have been reported. One clinical diagnostic laboratory has submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation and classified the variant as likely benign. Based on the evidence outlined above, the variant was classified as benign. -
Likely benign, criteria provided, single submitter	clinical testing	Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine	Feb 22, 2017	c.874+13T>C in intron 7 of VCL: This variant is not expected to have clinical si gnificance because it is not located within the splice consensus sequence.
