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]

ACAD8 Gene-Disease associations (from GenCC):

• isobutyryl-CoA dehydrogenase deficiency
