Variant summary
Our verdict is Benign. Variant got -7 ACMG points: 0P and 7B. BP4_ModerateBP6BS2
The NM_014000.3(VCL):c.1555A>C(p.Ile519Leu) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00111 in 1,614,012 control chromosomes in the GnomAD database, including 2 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Synonymous variant affecting the same amino acid position (i.e. I519I) has been classified as Benign.

Dilated cardiomyopathy 1W Uncertain:1Benign:1
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. -

Variant summary: VCL c.1555A>C (p.Ile519Leu) results in a conservative amino acid change in the encoded protein sequence. Three of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 0.00073 in 253200 control chromosomes, predominantly at a frequency of 0.0012 within the Non-Finnish European subpopulation in the gnomAD database. The observed variant frequency within Non-Finnish European control individuals in the gnomAD database is approximately 48 fold of the estimated maximal expected allele frequency for a pathogenic variant in VCL causing Cardiomyopathy phenotype (2.5e-05), strongly suggesting that the variant is a benign polymorphism found primarily in populations of Non-Finnish European origin. The variant has been reported in the literature, without strong evidence for causality (Lopes_2013, Pugh_2014), and in one case was reported to co-occur with a truncating DSC2 variant and an in-frame deletion in MYBPC3 (Lopes_2013). To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Seven other ClinVar submitters (evaluation after 2014) cite the variant as benign/likely benign (n=5) or uncertain significance (n=2). Based on the evidence outlined above, the variant was classified as benign. -
The p.Ile519Leu variant in VCL is classified as benign because it has been ident ified in 0.1% (151/126708) of European chromosomes by the Genome Aggreagation Da tabase (gnomAD; http://gnomad.broadinstitute.org/; dbSNP rs141033098). ACMG/AMP Criteria applied: BA1. -
Primary familial dilated cardiomyopathy Uncertain:1
- -
Ventricular tachycardia Benign:1
- -
Cardiovascular phenotype Benign:1
This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
