Variant summary

Our verdict is Pathogenic. Variant got 11 ACMG points: 11P and 0B. PM2_SupportingPVS1PM3

This summary comes from the ClinGen Evidence Repository: The NM_000018.4(ACADVL):c.1357C>T (p.Arg453Ter) variant in ACADVL is a nonsense predicted to cause a premature stop codon in biologically relevant exon 14/20 leading to nonsense mediated decay in a gene in which loss-of-function is an established disease mechanism (PVS1: PMIDs 9973285, 11590124). This variant was detected and confirmed in-trans with the pathogenic c.1349G>A (p.R450H) in a patient with VLCAD-deficiency (PM3, PMID:33150772). This variant was also reported in one patient with a positive newborn screen for VLCAD-deficiency (PMID:26385305). The highest population minor allele frequency in gnomAD v2.1.1 is 0.00003 in the Latino population, which is lower than the ClinGen ACADVL Variant Curation Expert Panel threshold (<0.001) for PM2_Supporting (PM2_Supporting). The ACADVL Variant Curation Expert Panel VCEP classified the variant as pathogenic based on PVS1,PM3,PM2_Supporting.

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]

Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpOct 14, 2023This sequence change creates a premature translational stop signal (p.Arg453*) in the ACADVL gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in ACADVL are known to be pathogenic (PMID: 9973285, 11590124). This variant is present in population databases (rs794727113, gnomAD 0.003%). This premature translational stop signal has been observed in individual(s) with very long-chain acyl-CoA dehydrogenase deficiency (PMID: 17999356). ClinVar contains an entry for this variant (Variation ID: 194317). For these reasons, this variant has been classified as Pathogenic. -
