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]

Very long chain acyl-CoA dehydrogenase deficiency

Pathogenic:2Uncertain:2

Pathogenic, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Jan 31, 2024	This sequence change replaces cysteine, which is neutral and slightly polar, with serine, which is neutral and polar, at codon 607 of the ACADVL protein (p.Cys607Ser). This variant is present in population databases (rs200117742, gnomAD 0.04%). This missense change has been observed in individual(s) with clinical features of very long-chain acyl-CoA dehydrogenase deficiency (PMID: 32778825; Invitae; external communication). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. ClinVar contains an entry for this variant (Variation ID: 474892). 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%. For these reasons, this variant has been classified as Pathogenic. -
Uncertain significance, criteria provided, single submitter	clinical testing	Wong Mito Lab, Molecular and Human Genetics, Baylor College of Medicine	Nov 01, 2019	The NM_000018.3:c.1820G>C (NP_000009.1:p.Cys607Ser) [GRCH38: NC_000017.11:g.7224877G>C] variant in ACADVL gene is interpretated to be Uncertain Significance based on ACMG guidelines (PMID: 25741868). This variant has been reported. This variant meets the following evidence codes reported in the ACMG guidelines: PP3 -
