Variant summary

Our verdict is Likely pathogenic. Variant got 9 ACMG points: 9P and 0B. PM2_SupportingPVS1

This summary comes from the ClinGen Evidence Repository: The c.192del (p.Lys64fs) variant in ACADVL is a frameshift predicted to cause a premature stop codon in biologically relevant exon 3/20 leading to nonsense mediated decay in a gene in which loss-of-function is an established disease mechanism (PVS1: PMIDs 9973285, 11590124). The highest population minor allele frequency in gnomAD is 0.0001603 in the African population, which is lower than the ClinGen ACADVL Variant Curation Expert Panel threshold (<0.001) for PM2_Supporting, meeting this criterion (PM2_Supporting). At least one patient with positive newborn screen for very long chain acyl-coA dehydrogenase (VLCAD) deficiency has been reported with this variant (PMID:26385305). The ACADVL Variant Curation Expert Panel VCEP classified the variant as likely pathogenic based on PVS1+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 submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Jan 06, 2024	This sequence change creates a premature translational stop signal (p.Lys64Asnfs*53) 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 (rs771055189, gnomAD 0.02%). This premature translational stop signal has been observed in individual(s) with a positive newborn screening result for ACADVL-related disease (PMID: 26385305). ClinVar contains an entry for this variant (Variation ID: 553583). For these reasons, this variant has been classified as Pathogenic. -
