ACADVL VCEP

The c.623-8C>T variant in ACADVL is an intronic variant which occurs in the polypyrimidine tract of intron 7. The highest population minor allele frequency in gnomAD v2.1.1 is 0.0289 in the African/African American 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 2 in silico splicing predictors (SpliceAI, NNSplice) 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 Expert Panel: BA1, BP4 (VCEP specifications v2.0, approved on 09/16/2021).

BA1

MAF of 0.02890 with 14 homozygotes in the African population

BP4

SpliceAI has no delta scores over 0.02 and predicts no impact. NNSplice predicts no changes to splicing.
