SLC25A15 cDNA Clone – Solute Carrier Family 25 (Mitochondrial Carrier; Ornithine Transporter) Member 15 (Human)

This gene is a member of the mitochondrial carrier family. The encoded protein transports ornithine across the inner mitochondrial membrane from the cytosol to the mitochondrial matrix. The protein is an essential component of the urea cycle, and functions in ammonium detoxification and biosynthesis of the amino acid arginine. Mutations in this gene result in hyperornithinemia-hyperammonemia-homocitrullinuria (HHH) syndrome. There is a pseudogene of this locus on the Y chromosome.[provided by RefSeq, May 2009]

SLC25A15: Ornithine transport across inner mitochondrial membrane, from the cytoplasm to the matrix. Defects in SLC25A15 are the cause of hyperornithinemia- hyperammonemia-homocitrullinuria syndrome (HHH syndrome). It is an autosomal recessive disorder resulting in various neurologic symptoms, including mental retardation, spastic paraparesis with pyramidal signs, cerebellar ataxia, and episodic disturbance of consciousness or coma caused by hyperammonemia. It causes a functional impairment of the urea cycle. Belongs to the mitochondrial carrier family.
