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]

[GRCH38: NC_000017.11:g.7224399T>C] variant in ACADVL gene is interpretated to be Benign based on ACMG guidelines (PMID: 25741868). This variant has been reported. This variant meets the following evidence codes reported in the ACMG guidelines: BS1, BS2 -
Benign, criteria provided, single submitter	clinical testing	Illumina Laboratory Services, Illumina	Jan 13, 2018	This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease. -

Benign, reviewed by expert panel	curation	ClinGen ACADVL Variant Curation Expert Panel, ClinGen	Jun 27, 2023	The c.1605+6T>C variant in ACADVL is an intronic variant which occurs in intron 16. The highest population minor allele frequency in gnomAD v2.1.1 is 0.66 in European Finnish population, which is higher than the ClinGen ACADVL Variant Curation Expert Panel threshold (>=0.007) for BA1, and therefore meets this criterion (BA1). The results from in silico splicing predictors (SpliceAI) support that this variant does not affect splicing (BP4). In summary, this variant meets the criteria to be classified as benign 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 ExpertPanel: BA1, BP4. -
