  2. Ornithine translocase deficiency - Wikipedia

    en.wikipedia.org/wiki/Ornithine_translocase...

    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.

  3. Ornithine aminotransferase deficiency - Wikipedia

    en.wikipedia.org/wiki/Ornithine_aminotransferase...

    In some cases, affected individuals will present in the neonatal period with disease that closely mimics a classic urea cycle defect, such as ornithine transcarbamylase deficiency, as the block in ornithine metabolism leads to secondary dysfunction of the urea cycle.

  4. Transient hyperammonemia of the newborn - Wikipedia

    en.wikipedia.org/wiki/Transient_hyperammonemia...

    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.

    Disease involving amino acids (e.g. PKU, Tyrosinemia), organic acids, primary lactic acidosis, galactosemia, or a urea cycle disease 24 per 100,000 births [9] 1 in 4,200 [9] Lysosomal storage disease: 8 per 100,000 births [9] 1 in 12,500 [9] Peroxisomal disorder ~3 to 4 per 100,000 of births [9] ~1 in 30,000 [9] Respiratory chain-based ...

  6. Ornithine transcarbamylase deficiency - Wikipedia

    en.wikipedia.org/wiki/Ornithine_transcarbamylase...

    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.

  7. Hyperammonemia - Wikipedia

    en.wikipedia.org/wiki/Hyperammonemia

    Continuous renal replacement therapy (CRRT) is a remarkably effective mode of therapy in neonatal hyperammonemia, particularly in severe cases of Urea cycle defects like Ornithine transcarbamoylase (OTC) deficiency. Multidisciplinary team (MDT) collaboration is required to optimize this advanced treatment.

    Dr. Rebecca MacMillan, a vet with over 15 years of experience, says she regularly sees four skin conditions in particular: skin allergies, parasites, acute moist dermatitis, and endocrine disease.

  9. N-Acetylglutamate synthase deficiency - Wikipedia

    en.wikipedia.org/wiki/N-Acetylglutamate_synthase...

    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 ...
