✦ Synopsis

A new case of propionic acidemia is presented, paying special attention to the early symptoms of this disease, such as increased drowsiness, muscuIar hypotonia, poor feeding, hypothermia, metabolic acidosis, ketonuria and vomiting. Investigation by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS) revealed the excretion of fairly high amounts of 2-methyl-3-oxovaleric acid, a condensation product of two molecules of propionyl-CoA, as well as the known pathological metabolites such as propionic, 3-hydroxypropionic and methylcitric acids. Among the post mortem findings the histological studies of the liver were the most remarkable.
