ACADVL VCEP

The c.1532+2T>C variant in ACADVL occurs within the canonical splice donor/acceptor site (+/- 1,2) of intron 15. It is predicted to cause skipping of biologically-relevant-exon 15/20, resulting in a frameshift leading to nonsense mediated decay in a gene in which loss-of-function is an established disease mechanism (PVS1; PMIDs 9973285, 11590124). At least one individual with this variant was identified by newborn screen, but this information is insufficient to use toward classification (PMID: 26385305). The highest population minor allele frequency in gnomAD v2.1 is 0.00005440 in the East Asian population, which is lower than the ClinGen ACADVL Variant Curation Expert Panel threshold (<0.001) for PM2_Supporting, meeting this criterion (PM2_Supporting). In summary, this variant meets the criteria to be classified as likely 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, PM2_Supporting. (ACADVL VCEP specifications version 1; approved November 8, 2021)

PM2_Supporting

The highest population minor allele frequency in gnomAD v2.1 is 0.00005440 in the East Asian population, which is lower than the ClinGen ACADVL Variant Curation Expert Panel threshold (<0.001) for PM2_Supporting, meeting this criterion (PM2_Supporting).

PP4

At least one individual with this variant was identified by newborn screen, but this information is insufficient to use toward classification (PMID: 26385305).
