RCV002286685 | SCV002576752 | pathogenic | Very long chain acyl-CoA dehydrogenase deficiency | 2022-03-08 | reviewed by expert panel | curation | The NM_000018.4: c.103_112dup10 (p.Arg38ProfsTer24) variant in ACADVL is a frameshift variant predicted to cause a premature stop codon in biologically relevant exon 2/20 leading to nonsense mediated decay in a gene in which loss-of-function is an established disease mechanism (PVS1; PMIDs 9973285, 11590124). This variant has been detected in at least 2 individuals with very long chain acyl CoA dehydrogenase (VLCAD) deficiency identified by increased C14:1 levels by newborn screen and one of these individuals had an acylcarnitine analysis consistent with VLCAD deficiency (PP4_moderate; PMID: 29519241, 29768383). One of these individuals was homozygous for the variant (PM3_supporting; PMID: 29768383). This variant is absent from gnomAD v2.1.1 (PM2_supporting). In summary, this variant meets the criteria to be classified as pathogenic 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: PVS1, PP4_moderate, PM3_supporting, PM2_supporting (VCEP specifications v2.0, approved on 09/16/2021). |

RCV002286685 | SCV004538948 | pathogenic | Very long chain acyl-CoA dehydrogenase deficiency | 2023-04-09 | criteria provided, single submitter | clinical testing | This variant is present in population databases (no rsID available, gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Arg38Profs*24) 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 premature translational stop signal has been observed in individual(s) with VLCAD deficiency (PMID: 29519241, 29768383). For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 1707706). |
