Variant summary

Our verdict is Benign. Variant got -9 ACMG points: 0P and 9B. BA1BP4

This summary comes from the ClinGen Evidence Repository: The c.68G>A variant in ACADVL is a missense variant predicted to cause the substitution of arginine by glutamine at amino acid 23 (p.Arg23Gln). The highest population minor allele frequency in gnomAD v2.1.1 is 0.01223 in the Latino population, which is higher than the ClinGen ACADVL Variant Curation Expert Panel threshold (≥0.007) for BA1, and therefore meets this criterion (BA1). The computational predictor REVEL gives a score of 0.123, which is below the threshold of 0.5, evidence that does not predict a damaging effect on ACADVL function (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 Expert Panel: BA1, BP4 (VCEP specifications v2.0, approved on 09/16/2021).

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]

Benign, reviewed by expert panel	curation	ClinGen ACADVL Variant Curation Expert Panel, ClinGen	Mar 08, 2022	The c.68G>A variant in ACADVL is a missense variant predicted to cause the substitution of arginine by glutamine at amino acid 23 (p.Arg23Gln). The highest population minor allele frequency in gnomAD v2.1.1 is 0.01223 in the Latino population, which is higher than the ClinGen ACADVL Variant Curation Expert Panel threshold (≥0.007) for BA1, and therefore meets this criterion (BA1). The computational predictor REVEL gives a score of 0.123, which is below the threshold of 0.5, evidence that does not predict a damaging effect on ACADVL function (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 Expert Panel: BA1, BP4 (VCEP specifications v2.0, approved on 09/16/2021). -

Benign, criteria provided, single submitter	clinical testing	Illumina Laboratory Services, Illumina	Apr 28, 2017	This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases was too high to be consistent with this variant causing disease. Therefore, this variant is classified as benign. -
