From: Long-term outcomes in Ornithine Transcarbamylase deficiency: a series of 90 patients
Initial plasma markers (plasma ammonemia, glutamine and citrulline) compared to the control group and cognitive outcome in the 1 mth-16 y group. Cognitive outcome was based on an IQ < 80 or >80, revealing extensive overlap of the values among patients with different outcomes. a: Individual markers shown separately (in μM). b: A combined score based on ammonia, glutamine and citrulline levels at diagnosis as a borderline predictor of IQ in the 1 mth-16 y group (see text).
