Autosomal dominant GTP cyclohydrolase I deficiency (AD-GTPCHD) is a disease caused by dysfunction of GTP cyclohydrolase I, an enzyme that plays an important role in the synthesis of tetrahydrobiopterin, and, as a consequence, of dopamine. This condition is one of the six known causes of tetrahydrobiopterin deficiency and is the most frequently-reported cause of dopa-responsive dystonia. WebSpecifically, tetrahydrobiopterin is involved in the production of two neurotransmitters called dopamine and serotonin. Among their many functions, dopamine transmits …
