Genes affected

ACADVL (HGNC:92): (acyl-CoA dehydrogenase very long chain) The protein encoded by this gene is targeted to the inner mitochondrial membrane where it catalyzes the first step of the mitochondrial fatty acid beta-oxidation pathway. This acyl-Coenzyme A dehydrogenase is specific to long-chain and very-long-chain fatty acids. A deficiency in this gene product reduces myocardial fatty acid beta-oxidation and is associated with cardiomyopathy. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Pathogenic. Variant got 12 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 17-7224711-C-A is Pathogenic according to our data. Variant chr17-7224711-C-A is described in ClinVar as [Likely_pathogenic]. Clinvar id is 1725435.Status of the report is criteria_provided_single_submitter, 1 stars.

Significance: Likely pathogenic

Review Status: criteria provided, single submitter

Collection Method: clinical testing

NM_000018.3(ACADVL):c.1748C>A(S583*) is expected to be pathogenic in the context of very-long-chain acyl-CoA dehydrogenase deficiency. This variant is predicted to lead to an abnormal or absent protein product due to the creation of a premature termination codon in ACADVL, a gene where loss-of-function variants are known to be pathogenic. Please note: this variant was assessed in the context of healthy population screening. -
