Description
Catalytic Activity
ATP + L-citrulline + L-aspartate = AMP + diphosphate + N(omega)-(L-arginino)succinate.
Disease
Citrullinemia 1 (CTLN1) [MIM:215700]: The classic form of citrullinemia, an autosomal recessive disease characterized primarily by elevated serum and urine citrulline levels. Ammonia intoxication is another manifestation. It is a disorder of the urea cycle, usually manifesting in the first few days of life. Affected infants appear normal at birth, but as ammonia builds up in the body they present symptoms such as lethargy, poor feeding, vomiting, seizures and loss of consciousness. Less commonly, a milder form can develop later in childhood or adulthood. {ECO:0000269|PubMed:11708871, ECO:0000269|PubMed:11941481, ECO:0000269|PubMed:12815590, ECO:0000269|PubMed:14680976, ECO:0000269|PubMed:16475226, ECO:0000269|PubMed:1943692, ECO:0000269|PubMed:2358466, ECO:0000269|PubMed:7977368}. Note=The disease is caused by mutations affecting the gene represented in this entry.
