ACADVL VCEP

The c.865G>A (p.Gly289Arg) variant in ACADVL has been reported in the literature in patients with VLCADD and increased C14:1 acylcarnitine (PP4_moderate; PMID: 14517516, 23480858, 31031081, 32778825, 27209629). The variant has also been detected in compound heterozygote with truncating/pathogenic variants (PM3; PMID: 14517516, 23480858, 31031081). This variant is absent from gnomAD population database v2.1.1(PM2_Supporting). This variant causes significantly reduced enzyme activity (15% of WT) determined from a bacterial cell expression system and results in unstable protein product (PMID:23480858, PS3_supporting). The computational predictor REVEL gives a score of 0.824, which is above the threshold of 0.75, evidence that correlates with impact to ACADVL function (PP3). The ACADVL Variant Curation Expert Panel VCEP classified the variant as likely pathogenic based on (PS3_supporting, PM3, PM2_supporting, PP3, PP4_moderate).

PP3

REVEL = 0.824 (> 0.75)

PM3

2 patients with p.V243A 1 patient with p.I183Mfs* unknown phase points=1.5

PP4_Moderate

5 patient reports of VLCADD, including C14:1 range 1-3uM.

PS3_Supporting

15% VLCAD activity from E.coli expressed. Unstable protein product.

PM2_Supporting

minor allele frequency (MAF) <0.001
