Genes affected

DDAH1 (HGNC:2715): (dimethylarginine dimethylaminohydrolase 1) This gene belongs to the dimethylarginine dimethylaminohydrolase (DDAH) gene family. The encoded enzyme plays a role in nitric oxide generation by regulating cellular concentrations of methylarginines, which in turn inhibit nitric oxide synthase activity.
