Clinical description ASA can have a variable clinical picture with either a neonatal-onset or a late-onset at any age outside the newborn period. Long-term complications associated with both forms of ASA include chronic hepatomegaly, liver dysfunction fibrosis or cirrhosisneurocognitive deficits i. Late-onset ASA is usually triggered by an acute infection, stress or after high protein intake.
Only comments written in English can be processed. Defects in this step of the urea cycle lead to an accumulation of plasma ammonia, argininosuccinic acid, citrulline, and urinary orotic acid, and to a plasma arginine deficiency. Differential diagnoses include other urea cycle disorders such as carbamoyl-phosphate synthetase 1 deficiency, ornithine transcarbamylase deficiency, citrullinemia type I and arginase deficiency see these terms.
In those with frequent episodes of metabolic decompensation or with hyperammonemia even when following a protein-restricted diet, daily oral nitrogen scavenging therapy may be successful.

This enzyme catalyzes the aginosuccinica of argininosuccinic acid into arginine and fumarate during the fourth step of the urea cycle. Genetic counseling ASA is inherited in an autosomal recessive manner and genetic counseling arhinosuccinica advisable. The test is safe and presents no risk to your baby.

Diagnostic methods Diagnosis is based mainly on clinical findings and laboratory test results. The documents contained in this web site are presented for information purposes only. Linked to chemical reactions in the body to create energy and build tissue.
Prenatal diagnosis is possible in families with a known disease causing mutation on both alleles. Antenatal diagnosis Prenatal diagnosis is possible in families with a known disease causing mutation on both alleles. For all other comments, please send your remarks via contact us. A healthy carrier is a person who has one mutated arginosucconica while the other gene is not affected, arginsouccinica it does not manifest the disease. If untreated, worsening lethargy, seizures, coma and death may occur.
Early diagnosis plays a key role in the arginosuccinnica of these diseases. Patients often manifest liver dysfunction. Neonates with severe neonatal-onset ASA usually appear normal during the first hours after birth but within a few days present with severe hyperammonemia manifesting with lethargy, somnolence, refusal to feed, vomiting, arginosuccjnica and respiratory alkalosis. With early diagnosis and treatment, hyperammonemic episodes can be avoided but long-term complications neurocognitive impairment, hepatic disease and arterial hypertension are frequent and have a negative effect on life-expectancy and quality of life.
ASA can have a variable clinical picture with either a neonatal-onset or a late-onset at any age outside the newborn period. Preventing conditions that can cause serious illness, intellectual disability and even death. Early medical treatment can allow your child to have a normal life, or minimize the consequences of the disease.
Differential diagnosis Differential diagnoses include other urea cycle disorders such as carbamoyl-phosphate synthetase 1 deficiency, ornithine transcarbamylase deficiency, citrullinemia type I xrginosuccinica arginase deficiency see these terms.
Orphanet: Argininosuccinic aciduria
Molecular genetic testing confirms diagnosis. Orthotopic liver transplantation offers long-term relief of hyperammonemia but does not seem to sufficiently correct neurological complications. The material is in no way intended to replace professional medical care by a qualified specialist and should not be used as a basis for diagnosis or treatment. This study is complementary to screening methods based on metabolites that are made under the National Research Program Newborn.
These disorders if are identified and treated early, allow the healthy development of your baby or a better quality of life.
What diseases does this analysis? Only comments seeking arginosuvcinica improve the quality and accuracy of information on the Orphanet website are accepted. Management and treatment During an acute hyperammonemic episode, oral proteins must be avoided and intravenous I.
The diseases included in this analysis can be classified into the following groups:.

Arterial hypertension can be treated by restoring nitric oxide deficiency. The sample can even take up the first year of life. Prognosis With early diagnosis and treatment, hyperammonemic episodes can be avoided but long-term complications neurocognitive impairment, hepatic disease and arterial hypertension are frequent and have a negative effect on life-expectancy and quality of life.
