ACADVL VCEP

The NM_000018.4: c.521T>C (p.Val174Ala) in ACADVL is a missense variant predicted to cause substitution of valine by alanine at amino acid 174 (p.Val174Ala). The highest population minor allele frequency in GnomAD v4.0.0 is 0.0001 in African/African American population, which is lower than the ClinGen ACADVL Variant Curation Expert Panel threshold (<0.001) for PM2_Supporting, meeting this criterion (PM2_Supporting). This variant has been reported in the literature in an individual with an abnormal newborn screen who is an apparently heterozygous carrier for the variant (PMID: 24503138), but this information is insufficient to use toward classification. The computational predictor REVEL gives a score of 0.926, which is above the threshold of 0.75, evidence that correlates with impact to ACADVL function (PP3). 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, PP3 (ACADVL VCEP specifications version 1; approved November 9, 2021).

PM2_Supporting

The highest population minor allele frequency in GnomAD v4.0.0 is 0.0001 in African/African American population, which is lower than the ClinGen ACADVL Variant Curation Expert Panel threshold (<0.001) for PM2_Supporting, meeting this criterion (PM2_Supporting).

PP3

The computational predictor REVEL gives a score of 0.926, which is above the threshold of 0.75, evidence that correlates with impact to ACADVL function (PP3).
