Variant summary
Our verdict is Likely benign. The variant received -6 ACMG points: 0P and 6B. BP4_ModerateBS2
The NM_014000.3(VCL):c.1856C>T(p.Ala619Val) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000291 in 1,613,314 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/22 in silico tools predict 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. A619E) has been classified as Uncertain significance.

Dilated cardiomyopathy 1W Uncertain:2
This sequence change replaces alanine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 619 of the VCL protein (p.Ala619Val). 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. 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. ClinVar contains an entry for this variant (Variation ID: 568183). This missense change has been observed in individual(s) with dilated cardiomyopathy (PMID: 28611029). This variant is present in population databases (rs771628544, gnomAD 0.01%). -
This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. However, the evidence from the literature, in combination with allele frequency data from public databases where available, was not sufficient to rule this variant in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance. -
not provided Uncertain:1
Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant does not alter protein structure/function; This variant is associated with the following publications: (PMID: 28611029) -
Cardiovascular phenotype Uncertain:1
The c.1856C>T (p.A619V) alteration is located in exon 13 (coding exon 13) of the VCL gene. This alteration results from a C to T substitution at nucleotide position 1856, causing the alanine (A) at amino acid position 619 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
