  2. Hyperuricemia - Wikipedia

    en.wikipedia.org/wiki/Hyperuricemia

    Unless high blood levels of uric acid are determined in a clinical laboratory, hyperuricemia may not cause noticeable symptoms in most people. [5] Development of gout – which is a painful, short-term disorder – is the most common consequence of hyperuricemia, which causes deposition of uric acid crystals usually in joints of the extremities, but may also induce formation of kidney stones ...

  3. Uremia - Wikipedia

    en.wikipedia.org/wiki/Uremia

    Uremia is the condition of having high levels of urea in the blood. Urea is one of the primary components of urine.It can be defined as an excess in the blood of amino acid and protein metabolism end products, such as urea and creatinine, which would normally be excreted in the urine.

  4. 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.

  5. Hyperammonemia - Wikipedia

    en.wikipedia.org/wiki/Hyperammonemia

    Glycine toxicity causes hyperammonemia, which manifests as CNS symptoms and nausea. Transient blindness can also occur. [12] Congenital hyperammonemia is usually due to genetic defects in one of the enzymes of the urea cycle, such as ornithine transcarbamylase deficiency, which leads to lower production of urea from ammonia. [citation needed]

  6. Azotemia - Wikipedia

    en.wikipedia.org/wiki/Azotemia

    This is because urea is readily reabsorbed by the kidneys while creatinine is not. In congestive heart failure (a cause of pre-renal azotemia) or any other condition that causes poor perfusion of kidneys, the sluggish flow of glomerular filtrate results in excessive absorption of urea and elevation of its value in blood. Creatinine, however, is ...

  7. Argininemia - Wikipedia

    en.wikipedia.org/wiki/Argininemia

    Argininemia is an autosomal recessive urea cycle disorder where a deficiency of the enzyme arginase causes a buildup of arginine and ammonia in the blood.Ammonia, which is formed when proteins are broken down in the body, is toxic if levels become too high; the nervous system is especially sensitive to the effects of excess ammonia.

  8. 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.

  9. Citrullinemia - Wikipedia

    en.wikipedia.org/wiki/Citrullinemia

    Citrullinemia is an autosomal recessive urea cycle disorder that causes ammonia and other toxic substances to accumulate in the blood. [1] Two forms of citrullinemia have been described, both having different signs and symptoms, and are caused by mutations in different genes. Citrullinemia belongs to a class of genetic diseases called urea ...
