Criteria Specification Information

Evidence submitted by expert panel

ACADVL VCEP

The c.62+18G>A (NM_000018.4) variant in ACADVL is an intronic variant which is located in intron 1 on a weakly conserved nucleotide. The highest population minor allele frequency in gnomAD v2.1.1 is 0.0002 in Admixed American population, which is lower than the ClinGen ACADVL Variant Curation Expert Panel threshold (<0.001) for PM2_Supporting, meeting this criterion (PM2_Supporting). The results from in silico splicing predictors (SpliceSiteFinder and MaxEntScn) support that this variant does not affect splicing (BP4). Due to limited evidence, this variant is classified as a variant of uncertain significance 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: PM2_Supporting, BP4 (ACADVL VCEP specifications version 1; approved November 9, 2021).

Met criteria codes

• BP4: The results from in silico splicing predictors (SSF and MaxEnt) support that this variant does not affect splicing (BP4).
• PM2_Supporting: The highest population minor allele frequency in gnomAD v2.1.1 is 0.0002 in Admixed American population, which is lower than the ClinGen ACADVL Variant Curation Expert Panel threshold (<0.001) for PM2_Supporting, meeting this criterion (PM2_Supporting).
