ACIDURIA ARGINOSUCCINICA by Fernanda Ramírez on Prezi

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 members of aciduriia family. Long-term complications associated with both forms of ASA include chronic hepatomegaly, liver dysfunction fibrosis or cirrhosisneurocognitive deficits i.

A presentation of late-onset cognitive impairment or learning disabilities in the absence of hyperammonemic episodes has also been reported. NeonatalAll ages ICD A healthy carrier is a person who has one mutated gene while arginosufcinica other gene is not affected, so it does not manifest the disease.

ASA can have a variable clinical picture with either a neonatal-onset or a late-onset at any age outside the newborn period. This study is complementary to screening methods based on afiduria that are made under the National Research Program Newborn. Arterial hypertension can be treated by restoring nitric oxide deficiency. Also they require a confirmatory test. Patients often manifest liver dysfunction.

Management and treatment During an acute hyperammonemic episode, aciruria proteins must be avoided and intravenous I. Orthotopic liver transplantation offers long-term relief of hyperammonemia but does not seem to sufficiently correct neurological complications.

This enzyme catalyzes the conversion of argininosuccinic acid into arginine and fumarate during the fourth step of the urea cycle. Other search option s Alphabetical list.

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. The test is safe agginosuccinica presents no risk to your baby. Diagnostic methods Diagnosis is based mainly on clinical findings and laboratory test results.

Genetic counseling ASA is inherited in an autosomal recessive manner and genetic counseling is advisable.
