Mitochondriale Ornithin-Aminotransferase

Das OAT-Gen kodiert ein Protein, welches in der Matrix der Mitochondrien die Transaminierung Ornithin zu Glutamat synthetisiert. Mutationen führen zum autosomal rezessiven Ornithin-Aminotransferase-Mangel, der mit einer Ornithinämie einhergehen kann und sich in einer zunehmenden Nachblindheit, die bis zur völligen Erblindung führen kann, äußert.
