Mitochondrial ornithine aminotransferase
The OAT gene encodes a mitochondrial matrix enzyme that catalyzes thansamination of ornithin to glutamin. Mutations cause autosomal recessive ornithine aminotransferase deficiency which can be associated with ornithinemia and presents with poor night vision, which slowly progresses to total blindness.
