What does ASS1 stand for?
ASS1 (Argininosuccinate Synthase 1) is a Protein Coding gene. Diseases associated with ASS1 include Citrullinemia, Classic and Acute Neonatal Citrullinemia Type I. Among its related pathways are Amino Acid metabolism and Alanine and aspartate metabolism.
Where is the ASS1 gene located?
chromosome 9
There are approximately 10 to 14 copies of this gene including the pseudogenes scattered across the human genome, among which the one located on chromosome 9 appears to be the only functional gene for argininosuccinate synthetase….Argininosuccinate synthetase 1.

What is the function of arginase?
The arginases catalyze the divalent cation dependent hydrolysis of L-arginine to produce L-ornithine and urea. Although traditionally considered in terms of its role as the final enzyme of the urea cycle, the enzyme is found in a variety of nonhepatic tissues.
What is ASL deficiency?
Defect: Argininosuccinate Lyase (ASL) Deficiency, also known as Argininosuccinic Aciduria (AA), is the result of a mutated or deficient argininosuccinate lyase enzyme. This defective or deficient enzyme leads to inadequate ureagenesis, accumulation of argininosuccinic acid, and deficient endogenous arginine production.
What is Argininosuccinic aciduria?
Argininosuccinic aciduria is a rare genetic disorder characterized by deficiency or lack of the enzyme argininosuccinate lyase (ASL). This enzyme is one of six enzymes that play a role in the breakdown and removal of nitrogen from the body, a process known as the urea cycle.
What is argininosuccinate lyase deficiency?
Argininosuccinate lyase (ASL) is the enzyme that catalyzes the fourth step in the urea cycle, in which argininosuccinic acid is cleaved to produce arginine and fumarate. All 50 states in the US include ASL deficiency in their newborn screening programs.
Which foods contain arginase?
Seeds have a significant amount of arginine. Pumpkin seeds have one of the highest concentrations of arginine. One cup of dried pumpkin seeds contains 6.905 grams of the amino acid….This includes:
- Walnuts.
- Hazelnuts.
- Pecans.
- Peanuts.
- Almonds.
- Cashews.
- Brazil Nuts.
Is arginase secreted?
Myeloid cells also secrete arginase to the microenvironment (133), where it acts mainly locally due to short circulating half-life (134). Murine MDSCs deplete L-arg by increased uptake and intracellular degradation, in contrast to human MDSCs that mainly release arginase into the circulation (103).
What is arginase deficiency?
Description. Collapse Section. Arginase deficiency is an inherited disorder that causes the amino acid arginine (a building block of proteins) and ammonia to accumulate gradually in the blood. Ammonia, which is formed when proteins are broken down in the body, is toxic if levels become too high.
What causes Trichothiodystrophy?
What causes trichothiodystrophy? Trichothiodystrophy is caused by defective DNA repair and transcription and is inherited in an autosomal recessive pattern, meaning both parents must carry a copy of the mutated gene that causes trichothiodystrophy for a child to inherit the condition.
What is ornithine transcarbamylase?
Ornithine transcarbamylase deficiency is an inherited disorder that causes ammonia to accumulate in the blood. Ammonia, which is formed when proteins are broken down in the body, is toxic if the levels become too high.
How common is Argininosuccinic aciduria?
Argininosuccinic aciduria is a rare disorder that affects fewer than a thousand people in the United States. It is estimated to affect anywhere between approximately one in 70,000 to 1 in 218,000 live births.
