Zusammenfassung

Die Krankheitsgruppe umfasst 6 angeborene Stoffwechselstörungen, die mit einem Tetrahydrobiopterinmangel (BH4-Mangel) entweder aufgrund einer gestörten BH4-Biosynthese oder eines gestörten BH4-Recyclings einhergehen. Tetrahydrobiopterin (BH4) ist ein essenzieller Kofaktor bei der Biosynthese der Neurotransmitter Dopamin und Serotonin und bei der Umwandlung von Phenylalanin zu Tyrosin. Bei einem BH4-Mangel kommt es deshalb sekundär zu einem Dopamin- und Serotoninmangel und dadurch zu einem in der Regel sich frühkindlich manifestierenden neurologischen Krankheitsbild mit progredienter Verschlechterung bei fehlender Behandlung.
