Variant summary
Our verdict is Likely benign. The variant received -3 ACMG points: 1P and 4B. PP3BS2
The NM_014000.3(VCL):c.2006G>T(p.Arg669Leu) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000013 in 1,613,274 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. R669Q) has been classified as Uncertain significance.

Dilated cardiomyopathy 1W    Uncertain:1 
This sequence change replaces arginine, which is basic and polar, with leucine, which is neutral and non-polar, at codon 669 of the VCL protein (p.Arg669Leu). This variant is present in population databases (rs759771302, gnomAD 0.006%). This variant has not been reported in the literature in individuals affected with VCL-related conditions. ClinVar contains an entry for this variant (Variation ID: 1362419). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. 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. -
Cardiovascular phenotype    Uncertain:1 
The p.R669L variant (also known as c.2006G>T), located in coding exon 14 of the VCL gene, results from a G to T substitution at nucleotide position 2006. The arginine at codon 669 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. Based on the available evidence, the clinical significance of this variant remains unclear. -
