Variant summary
Our verdict is Likely benign. The variant received -2 ACMG points: 2P and 4B. PP3_ModerateBS2
The NM_014000.3(VCL):c.163G>T(p.Val55Phe) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000521 in 1,534,466 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. V55L) has been classified as Uncertain significance.

not specified Uncertain:1
The p.Val55Phe variant in VCL has not been previously reported in individuals wi th cardiomyopathy and data from large population studies is insufficient to asse ss the frequency of this variant. Computational prediction tools and conservatio n analysis suggest that this variant may impact the protein, though this informa tion is not predictive enough to determine pathogenicity. In summary, the clinic al significance of the p.Val55Phe variant is uncertain. -

Dilated cardiomyopathy 1W Uncertain:1
This sequence change replaces valine, which is neutral and non-polar, with phenylalanine, which is neutral and non-polar, at codon 55 of the VCL protein (p.Val55Phe). This variant is present in population databases (rs755441334, gnomAD 0.005%). 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: 229631). 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. -
