Catecholamine synthesis pathway. TH: tyrosine hydroxylase; AADC: aromatic amino acid decarboxylase; DBH: dopamine B-hydroxylase; PNMT: phenylethanolamine-N-methyltransferase; COMT: catechol-O-methyltransferase. Deficiency in dopamine B-hydroxylase leads to elevated dopamine levels in dopamine secreting pheochromocytomas.
