Two patients with hypoketotic hypoglycaemia and dicarboxylic aciduria are described. Studies of their urinary organic acids by gas chromatography-mass spectrometry (GC-MS) showed an excretion of dicarboxylic acids (adipic suberic and sebacic acids), unsaturated dicarboxylic acids (cis-octenedioic and decenedioic acids),5-hydroxyhexanoic acid, hexanoyl-glycine and suberylglycine. Deficiency of the medium chain acyl-CoA dehydrogenase (MCAD) in fibroblasts was documented for both children. Despite a similar presentation (hypoglycaemic coma), organic acid profile (dicarboxylic aciduria and suberylglycine excretion) and enzyme deficiency (MCAD), they did not respond similarly to glucose infusion.

Acyl-CoA dehydrogenases (ACADs) are a family of mitochondrial enzymes catalyzing the initial rate-limiting step in the beta-oxidation of fatty acyl-CoA. The reaction provides main source of energy for human heart and skeletal muscle. Eight human ACADs have been described. Deficiency of these enzymes, especially very long-chain acyl-CoA dehydrogenase (VLCAD), usually leads to severe human organic diseases, such as sudden death in infancy, infantile cardiomyopathy (CM), hypoketotic hypoglycemia, or hepatic dysfunction. By large-scale random sequencing, we identified a novel homolog of ACADs from human dendritic cell (DC) cDNA library. It contains an open reading frame (ORF) of 1866bp, which encodes a 621 amino acid protein. It shares approximately 47% amino acid identity and 65% similarity with human VLCAD. So, the novel molecule is named as acyl-CoA dehydrogenase-9 (ACAD-9), the ninth member of ACADs. The new gene consists of 18 exons and 17 introns, and is mapped to chromosome 3q26. It contains the two signatures shared by all members of the ACADs. ACAD-9 mRNA is ubiquitously expressed in most normal human tissues and cancer cell lines with high level of expression in heart, skeletal muscles, brain, kidney, and liver. Enzymatic assay proved that the recombinant ACAD-9 protein has the dehydrogenase activity on palmitoyl-coenzyme A (C16:0) and stearoyl-coenzyme A (C18:0). Our results indicate that ACAD-9 is a novel member of ACADs.

Mitochondrial fatty acid beta-oxidation is an important energy resource for many mammal tissues. Acyl-CoA dehydrogenases (ACADs) are a family of flavoproteins that are involved in the beta-oxidation of the fatty acyl-CoA derivatives. Deficiency of these ACADs can cause metabolic disorders including muscle fatigue, hypoglycaemia, hepatic lipidosis and so on. By large scale sequencing, we identified a cDNA sequence of 3960 base pairs with a typical acyl-CoA dehydrogenase function domain. RT-PCR result shows that it is widely expressed in human tissues, especially high in liver, kidney, pancreas and spleen. It is hypothesized that this is a novel member of ACADs family.

Isovaleric acidemia (IVA), an inborn error of leucine catabolism, is caused by mutations in the isovaleryl-CoA dehydrogenase (IVD) gene, resulting in the accumulation of derivatives of isovaleryl-CoA including isovaleryl (C5)-carnitine, the marker metabolite used for newborn screening (NBS). The inclusion of IVA in NBS programs in many countries has broadened knowledge of the variability of the condition, whereas prior to NBS, two distinct clinical phenotypes were known, an "acute neonatal" and a "chronic intermittent" form. An additional biochemically mild and potentially asymptomatic form of IVA and its association with a common missense mutation, c.932C>T (p.A282V), was discovered in subjects identified through NBS. Deficiency of short/branched chain specific acyl-CoA dehydrogenase (2-methylbutyryl-CoA dehydrogenase), a defect of isoleucine degradation whose clinical significance remains unclear, also results in elevated C5-carnitine, and may therefore be detected by NBS for IVA. Treatment strategies for the long-term management of symptomatic IVA comprise the prevention of catabolism, dietary restriction of natural protein or leucine intake, and supplementation with l-carnitine and/or l-glycine. Recommendations on how to counsel and manage individuals with the mild phenotype detected by NBS are required.
