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.

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

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
