7-Substituted pterins in humans with suspected pterin-4a-carbinolamine dehydratase deficiency : mechanism of formation via non-enzymatic transformation from 6-substituted pterins

, 1992
A recently described new form of hyperphenylalaninemia is characterized by the excretion of 7-substituted isomers of biopterin and neopterin and 7-oxo-biopterin in the urine of patients.
