report of 21 mutations that cause NAGS deficiency. A total of 10 disease-causing mutations are associated with acute neonatal hyperammonemia. The remaining mutations are found in patients with late onset disease. Residual enzymatic activities are included in this report and the deleterious effects of eight mutations are confirmed by expression studies
