3-Methylglutaconic aciduria (MGCA) is a group of metabolic disorders characterized by increased urinary excretion of 3-methylglutaconic acid and 3-methylglutaric acid. Five distinct forms of MGCA have been recognized. MGCA type 1 is caused by primary deficiency of the mitochondrial enzyme 3-methylglutaconyl-CoA hydratase (3-MGCH), resulting in a block of leucine degradation. In all other types, the activities of 3-MGCH and other enzymes of leucine degradation are normal and the MGCA is thought to be secondary to a defect in another pathway. MGCA type 2, also known as Barth syndrome, is an X-linked cardiomyopathy associated with skeletal myopathy, neutropenia, and growth retardation. MGCA type 3, also referred to as Costeff optic atrophy syndrome, is an autosomal recessive disorder caused by mutations in the gene OPA3. It is characterized by early-onset bilateral optic atrophy, later-onset extrapyramidal dysfunction. MGCA type 5 caused by mutation in the DNAJC19 gene, is characterized by early-onset dilated cardiomyopathy with conduction defects, nonprogressive cerebellar ataxia, testicular dysgenesis, and growth failure. MGCA type 4 is the unclassified type, which includes all other patients with MGCA.

3-methylglutaconic (3MGC) aciduria is associated with a growing number of discrete inborn errors of metabolism. Herein, an antibody-based approach to detection/quantitation of 3MGC acid has been pursued. When trans-3MGC acid conjugated keyhole limpet hemocyanin (KLH) was inoculated into rabbits a

The identification of (E)-2-methylglutaconic acid, a 'new' metabolite of isoleucine, is described. The substance was detected in urine samples from patients with propionic acidaemia, methylmalonic acidaemia and so-called beta-ketothiolase deficiency; in the majority of cases together with N-tiglylglycine.

High-resolution gas chromatography (HRGC) and gas chromatography/mass spectrometry (GC/MS) are the techniques of choice to determine the retention indices of more than 200 organic acids as their trimethylsilyl (TMS) or oxime-trimethylsilyl derivatives. Several types of apolar and semipolar fused-silica capillary

We report clinical and biological investigations in two patients (twin brothers) with 2-methylacetoacetyl-CoA thiolase deficiency. Main clinical features included important staturo-ponderal delay, frequent infectious rhinopharyngitis episodes and an acute metabolic acidosis at the age of 4 years, this metabolic decompensation
