  • Trifunctional protein deficiency
  • Very long-chain acyl-CoA dehydrogenase deficiency (VLCAD)
• Galactosemia
• Glucose-6-phosphate dehydrogenase deficiency (G6PD)
• Human immunodeficiency disease (HIV)
• Organic acid metabolism disorders:
  • 3-Hydroxy-3-methylglutaric aciduria (HMG)
  • 3-Methylcrotonyl-CoA carboxylase deficiency (3MCC)
  • Beta ketothiolase deficiency
