Description

This sequence change creates a premature translational stop signal (p.Met440Tyrfs*23) in the ACADVL gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in ACADVL are known to be pathogenic (PMID: 9973285, 11590124). This variant is not present in population databases (gnomAD no frequency). For these reasons, this variant has been classified as Pathogenic. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. ClinVar contains an entry for this variant (Variation ID: 595610). This premature translational stop signal has been observed in individual(s) with ACADVL-related conditions (PMID: 26385305).

Description

The c.1317dup (p.Met440fs) variant in ACADVL is a frameshift predicted to cause a premature stop codon in biologically relevant exon 13/20 leading to nonsense mediated decay in a gene in which loss-of-function is an established disease mechanism (PVS1: PMIDs 9973285, 11590124). This variant has been reported as a result of a positive newborn screening for VLCADD (PMID:26385305). This variant is also absent from gnomAD v2.1.1 (PM2_Supporting). The ACADVL Variant Curation Expert Panel VCEP classified the variant as likely pathogenic based on PVS1, PM2_Supporting.
