摘要
Analysis of pyrimidine synthesis de novo intermediates and pyrimidine degradation products in urine samples from a decompensated patient with an ornithine transcarbamylase deficiency showed a strikingly aberrant metabolic profile. Strongly elevated levels of N-carbamyl-aspartate, orotate and uracil were present whereas the concentration of uridine was only marginally increased. The level of pyrimidine excretion appeared to be independent of the ammonia levels in blood, which were only mildly increased.
