Hyperornithinämie-Hyperammonämie-Homocitrullinurie-Syndrom

Das HHH-Syndrom ist eine autosomal rezessive Erkrankung des Proteinstoffwechsels. Durch den Ausfall des mitochondrialen Ornithintransporters kommt es zu einer Hyperammonämie. Die sekundären Folgen sind eine gestörte zerebrale Entwicklung und Störungen der Gerinnung.
