Genes affected
ACADS (HGNC:90): (acyl-CoA dehydrogenase short chain) This gene encodes a tetrameric mitochondrial flavoprotein, which is a member of the acyl-CoA dehydrogenase family. This enzyme catalyzes the initial step of the mitochondrial fatty acid beta-oxidation pathway. Mutations in this gene have been associated with short-chain acyl-CoA dehydrogenase (SCAD) deficiency. Alternative splicing results in two variants which encode different isoforms. [provided by RefSeq, Oct 2014]

Deficiency of butyryl-CoA dehydrogenase Pathogenic:2
Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpDec 13, 2023This sequence change creates a premature translational stop signal (p.Gln137*) in the ACADS gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in ACADS are known to be pathogenic (PMID: 12736383, 18523805). This variant is present in population databases (rs752677472, gnomAD 0.0009%). This premature translational stop signal has been observed in individual(s) with short-chain acyl-coenzyme A dehydrogenase deficiency (PMID: 12736383). ClinVar contains an entry for this variant (Variation ID: 189087). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. For these reasons, this variant has been classified as Pathogenic. -
