Official Full Name
GTP cyclohydrolase 1
Background
This gene encodes a member of the GTP cyclohydrolase family. The encoded protein is the first and rate-limiting enzyme;in tetrahydrobiopterin (BH4) biosynthesis, catalyzing the conversion of GTP into 7,8-dihydroneopterin triphosphate.;BH4 is an essential cofactor required by aromatic amino acid hydroxylases as well as nitric oxide synthases. Mutations;in this gene are associated with malignant hyperphenylalaninemia and dopa-responsive dystonia. Several alternatively;spliced transcript variants encoding different isoforms have been described; however, not all variants give rise to a;functional enzyme.
