Hyperammonemia, developmental disabilities, long-term renal and hepatic effects, and case-fatality associated with the various forms of UCD. b. Correlation between glutamine, ammonia, liver function (biomarkers), severity scale, and IQ in terms of outcome. c. Interim events related to treatments (drugs, diet or liver transplant).
