Comments
  • FUNCTION: Bifunctional subunit.
  • CATALYTIC ACTIVITY: (3S)-3-hydroxyacyl-CoA = trans-2(or 3)-enoyl-CoA + H2O.
  • CATALYTIC ACTIVITY: (S)-3-hydroxyacyl-CoA + NAD+ = 3-oxoacyl-CoA + NADH.
  • PATHWAY: Lipid metabolism; fatty acid beta-oxidation.
  • SUBUNIT: Octamer of 4 alpha (HADHA) and 4 beta (HADHB) subunits.
  • SUBCELLULAR LOCATION: Mitochondrion.
  • DISEASE: Defects in HADHA are a cause of trifunctional protein deficiency (TFP deficiency) [MIM:609015]. The clinical manifestations are very variable and include hypoglycemia, cardiomyopathy and sudden death. Phenotypes with mainly hepatic and neuromyopathic involvement can also be distinguished. Biochemically, TFP deficiency is defined by the loss of all enzyme activities of the TFP complex.
  • DISEASE: Defects in HADHA are the cause of long-chain 3-hydroxyl-CoA dehydrogenase deficiency (LCHAD deficiency) [MIM:609016]. The clinical features are very similar to TFP deficiency. Biochemically, LCHAD deficiency is characterized by reduced long-chain 3-hydroxyl-CoA dehydrogenase activity, while the other enzyme activities of the TFP complex are normal or only slightly reduced.
  • DISEASE: Defects in HADHA are a cause of maternal acute fatty liver of pregnancy (AFLP) [MIM:609016]. AFLP is a severe maternal illness occurring during pregnancies with affected fetuses. This disease is associated with LCHAD deficiency and characterized by sudden unexplained infant death or hypoglycemia and abnormal liver enzymes (Reye-like syndrome).
  • SIMILARITY: In the N-terminal section; belongs to the enoyl-CoA hydratase/isomerase family.
  • SIMILARITY: In the central section; belongs to the 3-hydroxyacyl-CoA dehydrogenase family.
  • WEB RESOURCE: Name=GeneReviews; URL="http://www.genetests.org/query?gene=HADHA";.
