The documents contained in this web site are presented for information purposes only. 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. Knowing the presence of this mutation is a valuable asset because with the proper genetic counseling is possible to prevent occurrence of these diseases in the future new acidudia of the family.

It does not constitute advice or advice regarding any kind of diagnosis, or substitute for consultation with your doctor. How is the analysis different of others? 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.
The diseases included in this analysis can be classified into the following groups: Antenatal acidduria Prenatal diagnosis is possible in families with a known disease causing mutation on both alleles.
Preventing conditions that can cause serious illness, intellectual disability and even death. Additional information Further information on this disease Classification s 2 Gene s 1 Clinical signs and symptoms Publications in PubMed Other website s This enzyme catalyzes the conversion of argininosuccinic acid into arginine and fumarate during the fourth step of the urea cycle. 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.
Linked to chemical reactions in the body to create energy and build tissue. Arterial hypertension can be treated by restoring nitric oxide deficiency. 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. For all other comments, please send your remarks via contact us. Late-onset ASA is usually triggered by an acute infection, stress or after high protein intake.
This information only has an educational purpos. Prenatal diagnosis is possible in families with a known disease causing mutation on both alleles.
The sample can even take up the first year of life. NeonatalAll ages ICD Only comments written in English can be processed. 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.
Newborn screening for ASA is available in the U.

Genetic counseling ASA is inherited in an autosomal recessive manner and genetic counseling is advisable. Diagnostic methods Diagnosis is based mainly on clinical findings and laboratory test results. 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 technology makes it possible to analyze 92 genes associated with different disease from a single drop of blood obtained at the time of birth. Management and treatment During an acute hyperammonemic episode, afiduria proteins must be avoided and intravenous I.
Some patients can be asymptomatic. A presentation of late-onset cognitive impairment or learning disabilities in the acidurai of hyperammonemic episodes has also been reported.
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.

The test is safe and presents no risk to your baby. During an acute hyperammonemic episode, oral arginosyccinica must be avoided and intravenous I.
Diagnosis is based mainly on clinical findings and laboratory test results. Long-term complications associated with both forms of ASA include chronic hepatomegaly, liver dysfunction fibrosis or cirrhosisneurocognitive deficits i. ASA can have a variable clinical picture with either a neonatal-onset or a late-onset at any age outside the newborn period. Health care resources for this disease Expert centres Diagnostic tests 92 Patient organisations 42 Orphan drug s 6.
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. Differential diagnosis Differential diagnoses include other urea cycle disorders such as carbamoyl-phosphate synthetase 1 deficiency, ornithine transcarbamylase deficiency, citrullinemia type I aginosuccinica arginase deficiency see these terms.
Neonates with severe arrginosuccinica 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, tachypnea and respiratory alkalosis.
Summary and related texts. Also they require a confirmatory test. The results are reported within 10 working days after sampling.
