报告了一种迄今未描述的疾病,其表现为精神发育迟滞、瓜氨酸尿、高瓜氨酸血症和高氨血症。饮食研究表明,蛋白质摄入量与尿瓜氨酸排泄量之间存在直接关系。瓜氨酸排泄以溢流机制发生,血浆瓜氨酸维持在约25 mg/100 ml。负荷研究表明,鸟氨酸尿素循环功能正常;高吸收后血氨水平表明,几乎没有尿素形成的储备能力。
A heretofore undescribed disorder manifested by mental retardation, citrullinuria, hypercitrullinemia, and hyperammonemia is reported. Dietary studies show a direct relationship between protein intake and urinary citrulline excretion. Citrulline excretion occurs as an overflow mechanism with plasma citrulline being maintained at about 25 mg/100 ml. Loading studies suggest that the ornithine urea cycle is functioning; high post-absorptive blood ammonia levels indicate that little reserve capacity for urea formation is present.
