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]

Likely pathogenic, criteria provided, single submitter	clinical testing	Baylor Genetics	Sep 30, 2023	- -
Likely pathogenic, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Aug 24, 2023	This sequence change replaces glutamine, which is neutral and polar, with proline, which is neutral and non-polar, at codon 368 of the ACADVL protein (p.Gln368Pro). This variant is present in population databases (rs776063244, gnomAD 0.0009%). This missense change has been observed in individual(s) with VLCAD deficiency (PMID: 31031081). ClinVar contains an entry for this variant (Variation ID: 439360). 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. In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. -
Likely pathogenic, 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.1103A>C (NP_000009.1:p.Gln368Pro) [GRCH38: NC_000017.11:g.7223158A>C] variant in ACADVL gene is interpretated to be Likely Pathogenic based on ACMG guidelines (PMID: 25741868). This variant has been reported. This variant meets the following evidence codes reported in the ACMG guidelines: PS3, PM1, PP3 -

Uncertain significance, criteria provided, single submitter	clinical testing	Myriad Genetics, Inc.	Nov 11, 2021	NM_000018.3(ACADVL):c.1103A>C(Q368P) is a missense variant classified as a variant of uncertain significance in the context of very-long-chain acyl-CoA dehydrogenase deficiency. Q368P has been observed in cases with relevant disease (PMID: 26385305, 31031081). Functional assessments of this variant are not available in the literature. Q368P has been observed in population frequency databases (gnomAD: NFE 0.01%). In summary, there is insufficient evidence to classify NM_000018.3(ACADVL):c.1103A>C(Q368P) as pathogenic or benign. Please note: this variant was assessed in the context of healthy population screening. -
