Summaries for ACAD8 Gene

Entrez Gene Summary for ACAD8 Gene

  • 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]

GeneCards Summary for ACAD8 Gene

ACAD8 (Acyl-CoA Dehydrogenase Family, Member 8) is a Protein Coding gene. Diseases associated with ACAD8 include isobutyryl-coa dehydrogenase deficiency and 2-methylbutyrylglycinuria.
