Ornithine transcarbamylase deficiency also known as OTC deficiency is the most common urea cycle disorder in humans. Ornithine transcarbamylase, the defective enzyme in this disorder, is the final enzyme in the proximal portion of the urea cycle, responsible for converting carbamoyl phosphate and ornithine into citrulline.
Since the etiology is unconfirmed, diagnosis is generally accomplished when there is hyperammonemia present within 24–36 hours of birth and urea cycle defects can be excluded. [5] Organic acidemias and other metabolic errors must also be excluded. The diagnostic criteria for hyperammonemia is ammonia blood levels higher than 35 μmol/L.

Ornithine translocase deficiency belongs to a class of metabolic disorders referred to as 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.
About Urea Cycle Disorders A urea cycle disorder is caused by a genetic mutation—a change in a person’s genes—that leads to a deficiency of one of the enzymes needed to metabolize protein. These missing or reduced enzymes make the process less efficient, allowing ammonia to build up in the bloodstream.
N-acetyl glutamate is required for the urea cycle to take place. Deficiency in N-acetylglutamate synthase or a genetic mutation in the gene coding for the enzyme will lead to urea cycle failure in which ammonia is not converted to urea, but rather accumulated in blood leading to the condition called type I hyperammonemia. This is a severe ...
