Genes affected
ACAD9 (HGNC:21497): (acyl-CoA dehydrogenase family member 9) This gene encodes a member of the acyl-CoA dehydrogenase family. Members of this family of proteins localize to the mitochondria and catalyze the rate-limiting step in the beta-oxidation of fatty acyl-CoA. The encoded protein is specifically active toward palmitoyl-CoA and long-chain unsaturated substrates. Mutations in this gene cause acyl-CoA dehydrogenase family member type 9 deficiency. Alternate splicing results in multiple transcript variants.[provided by RefSeq, Mar 2010]

Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpJan 09, 2024This sequence change affects the initiator methionine of the ACAD9 mRNA. The next in-frame methionine is located at codon 124. This variant is present in population databases (rs773949927, gnomAD 0.003%). Disruption of the initiator codon has been observed in individual(s) with mitochondrial complex I deficiency (PMID: 26669660, 30025539). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. ClinVar contains an entry for this variant (Variation ID: 1439431). This variant disrupts a region of the ACAD9 protein in which other variant(s) (p.Phe44Ile) have been observed in individuals with ACAD9-related conditions (PMID: 21057504). This suggests that this is a clinically significant region of the protein, and that variants that disrupt it are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic. -
