The development of autosomal dominant DOPA-responsive dystonia (AD-DRD) is stipulated by mutation in GTP-cyclohydrolase I gene. GTP-cyclohydrolase I is the first and key enzyme of tetrahydrobiopterin biosynthesis. Its deficiency in nigrostriatal dopaminergic neurons cause a decrease in tyrosine hydroxylase activity and therefore dopamine deficiency. However, administration of low doses of dopamine can control the development of AD-DRD. Determination of GTP-cyclohydrolase I activity in mononuclear blood cells is convenient diagnostic method
