GeneID: 154


Common Name: ARG1 Type: Gene
Chromosome: 6 (NC_000006.12) Locus: NG_007086.2 (ARG1)
HUGO Symbol: ARG1 Full Name: arginase 1
Exons: 8 Introns: 7

Arginase catalyses the hydrolysis of arginine to ornithine and urea, thus playing an essential role in the regulation of nitric oxide and polyamine metabolism. The type I isoform encoded by this gene is localised to the cytoplasm and expressed predominately in the liver. Enzyme deficiency results in argininemia characterized by hyperammonemia, progressive mental impairement, spasticity and growth retardation. Polymorphisms in the ARG1 gene associated with the HbF response to hydroxyurea (HU) in sickle cell patients. Two transcript variants encoding different isoforms have been found for this gene.

Synonyms: arginase, liver
