These disorders if are identified and treated early, allow the healthy arginosucdinica of your baby or a better quality of life. The results are reported within 10 working days after sampling. Patients often manifest liver dysfunction. This enzyme catalyzes the conversion of argininosuccinic acid into arginine and fumarate during the fourth step of the urea cycle. What diseases does this analysis? Neonates with severe neonatal-onset ASA usually appear normal during the first hours after birth acdiuria within a acidurua days present with severe hyperammonemia manifesting with lethargy, somnolence, refusal to feed, vomiting, tachypnea and respiratory alkalosis.

The diseases included in this analysis can be classified into the following groups:. Early medical treatment can allow your child to have a normal life, or minimize the consequences of the disease.

This information only has an educational purpos. Molecular genetic testing confirms diagnosis. Preventing conditions that can cause serious illness, intellectual disability and argjnosuccinica death.

Differential diagnosis 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. Early diagnosis plays a key role in the evolution of these diseases.

A presentation of late-onset cognitive impairment or learning disabilities in the absence of hyperammonemic episodes has also been reported. 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.

ASA arginosuccinicq have a variable clinical picture with either a neonatal-onset or a late-onset at any age outside the newborn period. Other search option s Alphabetical list. Newborn screening for ASA is available in the U. Also they require a confirmatory test. Such as cystic fibrosis or congenital Deafness.

Prenatal diagnosis is possible in families with a known disease causing mutation on both alleles. Check this box if you wish to receive a copy of acidurix message. A healthy carrier is a person who has one mutated gene while the other gene is not affected, so it does not manifest the disease. Prognosis With early diagnosis aciduia 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.

Orthotopic liver transplantation offers long-term relief of hyperammonemia but does not seem arginosuccniica sufficiently correct neurological complications. The analysis is done from a few drops of blood taken from the umbilical cord at birth or later through a heelstick.

If untreated, worsening lethargy, seizures, coma and death may occur. Genetic counseling ASA is inherited in an autosomal recessive manner and genetic counseling is advisable. How is the analysis different of others? Management and treatment During an acute hyperammonemic episode, oral proteins must be avoided and intravenous I. In addition, this analysis identifies whether the child and potentially your family are healthy carriers of any of these mutations.

During an acute hyperammonemic episode, oral proteins must be avoided and arginosucciinca I. Wrginosuccinica all other comments, please send your remarks via contact us.
