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]

Significance:Pathogenic

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces cysteine, which is neutral and slightly polar, with tyrosine, which is neutral and polar, at codon 607 of the ACADVL protein (p.Cys607Tyr). This variant is present in population databases (no rsID available, gnomAD 0.01%). This missense change has been observed in individual(s) with very long-chain acyl-CoA dehydrogenase deficiency (Invitae). ClinVar contains an entry for this variant (Variation ID: 235307). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt ACADVL protein function with a positive predictive value of 95%. This variant disrupts the p.Cys607 amino acid residue in ACADVL. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 32778825; Invitae; external communication). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic. -
