Genes affected

ACAD8 (HGNC:87): (acyl-CoA dehydrogenase family member 8) This gene encodes a member of the acyl-CoA dehydrogenase family of enzymes that catalyze the dehydrogenation of acyl-CoA derivatives in the metabolism of fatty acids or branch chained amino acids. The encoded protein is a mitochondrial enzyme that functions in catabolism of the branched-chain amino acid valine. Defects in this gene are the cause of isobutyryl-CoA dehydrogenase deficiency.[provided by RefSeq, Nov 2009]

This sequence change affects the initiator methionine of the ACAD8 mRNA. The next in-frame methionine is located at codon 39. This variant is present in population databases (rs751940610, gnomAD 0.01%). Disruption of the initiator codon has been observed in individual(s) with Isobutyryl-CoA dehydrogenase deficiency (PMID: 17924841, 24635911; Invitae). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. -
