mortality/aging
• homozygous mutant mice stop gaining weight at about 10 hours after birth, and usually die prior to 24 hours after birth

homeostasis/metabolism
• 16-hr-old homozygous mutant mice display a significantly higher plasma concentration of citrulline and a decreased level of arginine
• 16-hr-old homozygous mutant mice display an overall 2- to 4-fold increase in the plasma levels of almost all amino acids
• notably, 16-hr-old homozygous mutant mice display a 30-fold increase in aspartic acid, an effect not observed in humans with citrullinemia
• 16- to 19-hr-old homozygous mutant mice have a plasma ammonia concentration that is 16 times greater that of wild-type siblings
