Abstract

Correlation of the response to a load of tetrahydrobiopterin (BH₄) in dihydropterin reductase (DHPR) deficient patients to the type of mutation in these patients has led to the conclusion that 4 patients without mutant DHPR molecules in their cells respond to the BH₄ load, whereas 3 patients with mutant DHPR in their cells do not respond. Intravenous injection of BH₄ in 1 of the cases not responding to BH₄ again showed no response.
