Variant summary

Our verdict is Likely benign. Variant got -1 ACMG points: 1P and 2B. PP2BP4BS1_Supporting

The NM_014000.3(VCL):c.854G>T(p.Arg285Leu) variant causes a missense change. The variant allele was found at a frequency of 0.0000415 in 1,613,992 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign 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. R285C) 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]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -1 ACMG points.

PP2

Missense variant where missense usually causes diseases, VCL

BP4

Computational evidence support a benign effect (MetaRNN=0.26523495).

BS1

Variant frequency is greater than expected in population eas. gnomad4_exome allele frequency = 0.0000451 (66/1461810) while in subpopulation EAS AF= 0.00164 (65/39698). AF 95% confidence interval is 0.00132. There are 0 homozygotes in gnomad4_exome. There are 28 alleles in male gnomad4_exome subpopulation. Median coverage is 32. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

The p.R285L variant (also known as c.854G>T), located in coding exon 7 of the VCL gene, results from a G to T substitution at nucleotide position 854. The arginine at codon 285 is replaced by leucine, an amino acid with dissimilar properties. This amino acid position is conserved. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
