Variant summary
Our verdict is Uncertain significance. The variant received 1 ACMG points: 2P and 1B. PM2BP4
The NM_014000.3(VCL):c.1861A>C(p.Asn621His) variant causes a missense change. The variant allele was found at a frequency of 0.00000124 in 1,613,344 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. N621K) has been classified as Uncertain significance.

Dilated cardiomyopathy 1W Uncertain:1
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: 536708). This variant has not been reported in the literature in individuals affected with VCL-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces asparagine, which is neutral and polar, with histidine, which is basic and polar, at codon 621 of the VCL protein (p.Asn621His). -
not provided Uncertain:1
Has not been previously published as pathogenic or benign to our knowledge; Reported in ClinVar as a variant of uncertain significance by another clinical laboratory (ClinVar Variant ID# 536708; Landrum et al., 2016); Not observed in large population cohorts (Lek et al., 2016); In silico analysis, which includes protein predictors and evolutionary conservation, supports a deleterious effect -
