Description

This sequence change creates a premature translational stop signal (p.Pro89Hisfs*28) in the ACADVL gene. It is expected to result in an absent or disrupted protein product. This variant is present in population databases (rs771808680, ExAC 0.01%). This variant has been reported in an individual with newborn screening results suggestive of very long chain acyl-coA dehydrogenase deficiency (PMID: 26385305). Loss-of-function variants in ACADVL are known to be pathogenic (PMID: 9973285, 11590124). For these reasons, this variant has been classified as Pathogenic.
