SLC25A15

Functionⁱ

Ornithine-citrulline antiporter. Connects the cytosolic and the intramitochondrial reactions of the urea cycle by exchanging cytosolic ornithine with matrix citrulline (PubMed:12807890).

The stoichiometry is close to 1:1 (By similarity).

Pathology & Biotechⁱ

Involvement in diseaseⁱ

Hyperornithinemia-hyperammonemia-homocitrullinuria syndrome (HHHS)8 Publications

The disease is caused by variants affecting the gene represented in this entry.

Disease descriptionAn autosomal recessive disorder of the urea cycle characterized by onset in early life. The acute phase of the disease is characterized by vomiting, ataxia, lethargy, confusion, and coma. Chronic clinical manifestations include hypotonia, developmental delay, progressive encephalopathy with mental regression, and spastic paraparesis with pyramidal signs.
