GTP cyclohydrolase I deficiency
Synonyms: GTPCH deficiency | Hyperphenylalaninemia due to GTP cyclohydrolase deficiency
GTP-cyclohydrolase I deficiency an autosomal recessive genetic disorder is one of the causes of malignant hyperphenylalaninemia due to tetrahydrobiopterin deficiency. Not only does tetrahydrobiopterin deficiency cause hyperphenylalaninemia it is also responsible for defective neurotransmission of monoamines because of malfunctioning tyrosine and tryptophan hydroxylases both tetrahydrobiopterin-dependent hydroxylases.
