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 ...
As one of the urea cycle disorders, citrullinemia type I needs to be distinguished from the others: carbamoyl phosphate synthetase deficiency, argininosuccinic acid lyase deficiency, ornithine transcarbamylase deficiency, arginase deficiency, and N-Acetylglutamate synthase deficiency. Other diseases that may appear similar to CTLN1 include the ...
Citrullinemia type II [1] Inborn errors of organic acid metabolism. Methylmalonic acidemia (Cbl C,D) [1] Malonic acidemia [1] 2-Methyl 3-hydroxy butyric aciduria [1] Isobutyryl-CoA dehydrogenase deficiency [1] 2-Methylbutyryl-CoA dehydrogenase deficiency [1] 3-Methylglutaconyl-CoA hydratase deficiency [1] Glutaric acidemia type II
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.
An accumulation of ammonia during the first few days of life leads to poor feeding, vomiting, seizures, and the other signs and symptoms of type I citrullinemia. Treatment for this defect includes a low-protein diet and dietary supplementation with arginine and phenylacetate. Arginine allows the urea cycle to complete itself, creating the ...
Ornithine translocase deficiency, also called hyperornithinemia-hyperammonemia-homocitrullinuria (HHH) syndrome, [1] is a rare autosomal recessive [2] urea cycle disorder affecting the enzyme ornithine translocase, which causes ammonia to accumulate in the blood, a condition called hyperammonemia.
Hartnup disease (also known as "pellagra-like dermatosis" [1] and "Hartnup disorder" [2]) is an autosomal recessive [3] metabolic disorder affecting the absorption of nonpolar amino acids (particularly tryptophan that can be, in turn, converted into serotonin, melatonin, and niacin).
Hemolytic disease of the newborn (anti-Rhc) can range from a mild to a severe disease. It is the third most common cause of severe HDN. Rh disease is the most common and hemolytic disease of the newborn (anti-Kell) is the second most common cause of severe HDN. It occurs more commonly in women who are Rh D negative.
