Variant summary

Our verdict is Uncertain significance. The variant received 2 ACMG points: 2P and 0B. PP3PM2_Supporting

This summary comes from the ClinGen Evidence Repository: The c.1103A>C (NM_000018.4) variant in ACADVL is a missense variant predicted to cause substitution of glutamine by proline at amino acid 368 (p.Gln368Pro). Several individuals with this variant were identified by newborn screen or were identified in individuals without additional laboratory data to support affected status, so this information is insufficient to use toward classification (PMID:26385305, 31031081). This variant is only detected on one allele in gnomAD v2.1.1, which is lower than the ClinGen ACADVL Variant Curation Expert Panel threshold (<0.001) for PM2_Supporting, meeting this criterion (PM2_Supporting). The computational predictor REVEL gives a score of 0.98, which is above the threshold of 0.75, evidence that correlates with impact to ACADVL function (PP3). In summary, this variant meets the criteria to be classified as a variant of uncertain significance for autosomal recessive very long chain acyl-CoA dehydrogenase (VLCAD) deficiency based on the ACMG/AMP criteria applied, as specified by the ClinGen ACADVL Variant Curation Expert Panel: PM2_Supporting, PP3 (ACADVL VCEP specifications version 1; approved November 9, 2021).

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]

ACADVL links:

MIR324 (HGNC:31767): (microRNA 324) microRNAs (miRNAs) are short (20-24 nt) non-coding RNAs that are involved in post-transcriptional regulation of gene expression in multicellular organisms by affecting both the stability and translation of mRNAs. miRNAs are transcribed by RNA polymerase II as part of capped and polyadenylated primary transcripts (pri-miRNAs) that can be either protein-coding or non-coding. The primary transcript is cleaved by the Drosha ribonuclease III enzyme to produce an approximately 70-nt stem-loop precursor miRNA (pre-miRNA), which is further cleaved by the cytoplasmic Dicer ribonuclease to generate the mature miRNA and antisense miRNA star (miRNA*) products. The mature miRNA is incorporated into a RNA-induced silencing complex (RISC), which recognizes target mRNAs through imperfect base pairing with the miRNA and most commonly results in translational inhibition or destabilization of the target mRNA. The RefSeq represents the predicted microRNA stem-loop. [provided by RefSeq, Sep 2009]

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. -

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). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is expected to disrupt ACADVL protein function with a positive predictive value of 80%. 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. -
