    What are the genetic changes related to ornithine translocase deficiency ?
    ### Response:
    Mutations in the SLC25A15 gene cause ornithine translocase deficiency.  Ornithine translocase deficiency belongs to a class of genetic diseases called urea cycle disorders. The urea cycle is a sequence of reactions that occurs in liver cells. This cycle processes excess nitrogen, generated when protein is used by the body, to make a compound called urea that is excreted by the kidneys.
