Criteria Specifications for this VCEP
Evidence submitted by expert panel
ACADVL VCEP
The c.37C>T (p.Gln13Ter) variant in ACADVL is a nonsense variant predicted to cause a premature stop codon in biologically-relevant-exon 1/20 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 patient with this variant displayed VLCAD enzyme levels of <20% of normal, which is highly specific for very long chain acyl CoA dehydrogenase (VLCAD) deficiency (PP4_Moderate; PMIDs: 20060901, 17999356). 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 VLCAD deficiency based on the ACMG/AMP criteria applied, as specified by the ClinGen ACADVL Variant Curation Expert Panel: PVS1, PP4_Moderate, PM2_Supporting (ACADVL VCEP specifications version 1; approved November 8, 2021).
Met criteria codes
PM2_Supporting
Variant was not found in gnomAD. Used PM2_Supporting based on SVI guidance.
PP4_Moderate
Detected in patient with <20% VLCAD activity (PMID: 20060901, 17999356)
PVS1
The nonsense variant is expected to result in LOF, which is a known mechanism of disease for ACADVL. The next in frame methionine is at codon 77.
Not Met criteria codes
PP2
Not a missense variant
PM1
Amino acid 13 is not located in a mutational hotspot
PM5
The variant is nonsense, not missense
BA1
Variant was not found in gnomAD
BS1
Variant was not found in gnomAD
BP1
Not a missense variant
PS1
No other nonsense change was found for codon 13.
