Argininosuccinic aciduria. A developmental and biochemical case study
Journal of the Neurological Sciences
|August 1, 1983
Summary
Argininosuccinic aciduria detected via newborn screening shows long-term challenges. Early treatment with diet changes and arginine supplementation led to borderline intelligence and mild ataxia in a 7-year-old patient.
Area of Science:
- Biochemistry
- Genetics
- Pediatrics
Background:
- Argininosuccinic aciduria (ASA) is an inherited urea cycle disorder.
- Early detection through newborn screening is crucial for timely intervention.
- Management involves dietary protein restriction and arginine supplementation.
Observation:
- A patient diagnosed with ASA in infancy was monitored for over 7 years.
- Treatment initiated at 8 months was intermittent.
- Normal psychomotor development was observed until age 3, with borderline intelligence and mild cerebellar ataxia by age 7.3.
- Below-normal physical growth was noted.
Findings:
- Intermittent treatment adherence impacted long-term outcomes.
- Biochemical abnormalities persisted despite treatment.
- The study details metabolic investigations and treatment effects in a long-term pediatric case.
Implications:
- Highlights the importance of consistent treatment adherence for urea cycle disorders.
- Suggests potential long-term neurodevelopmental challenges even with early diagnosis.
- Informs management strategies for argininosuccinic aciduria in pediatric patients.

01:48ATP Synthase: Mechanism
In animals, the mitochondrial F1F0 ATP synthase is the key protein that synthesizes ATP molecules through a complex catalytic mechanism. While the nuclear genome encodes the majority of ATP synthase subunits, the mitochondrial genome encodes some of the enzyme's most critical components. The formation of this multi-subunit enzyme is a complex multi-step process regulated at the level of transcription, translation, and assembly. Defects in one or more of these steps can result in decreased ATP...
01:22Lysosomal Hydrolases
Lysosomes are the site for the degradation of macromolecules and biological polymers released during membrane trafficking events such as secretory, endocytic, autophagic, and phagocytic pathways. The membrane-enclosed area of the lysosome, called the lumen, contains hydrolytic enzymes active in an acidic environment. These acid hydrolases are functional at a pH between 4.5 and 5 and are involved in cellular processes such as cell signaling, energy metabolism, restoration of the plasma membrane,...
01:21Smooth Endoplasmic Reticulum
Smooth endoplasmic reticulum or smooth ER is a sub-organelle with specialized functions in animal cells and plant cells. It is often associated with the tubule morphology of the endoplasmic reticulum.
The ER provides optimal conditions for synthesizing steroid hormones and lipids, such as phospholipids and triglycerides. Traditionally, lipid metabolism was considered to be a smooth ER function. However, there is no direct evidence to prove that rough ER is completely excluded from lipid...

01:20Inborn Errors of Metabolism
Phenylketonuria (PKU) is a protein metabolism disorder characterized by high blood levels of the amino acid phenylalanine. This results from a mutation in the gene responsible for phenylalanine hydroxylase, an enzyme that converts phenylalanine into tyrosine. When this enzyme is deficient, phenylalanine builds up in the blood, leading to symptoms such as vomiting, rashes, seizures, growth deficiency, and severe mental retardation. An early diagnosis and a diet restricting phenylalanine intake...
01:29Amino Acid Biosynthetic Pathways
Amino acid biosynthesis is essential for cell growth, protein synthesis, and metabolic regulation. Cells generate essential and non-essential amino acids from metabolic intermediates to sustain vital biological functions. These intermediates originate from key metabolic pathways: glycolysis, the tricarboxylic acid (TCA) cycle, and the pentose phosphate pathway. Important precursors include α-ketoglutarate, pyruvate, oxaloacetate, phosphoenolpyruvate, and erythrose-4-phosphate, which provide...
01:28Biosynthesis of Nucleic Acids
Nucleic acid biosynthesis is a fundamental biochemical process that produces the purine and pyrimidine nucleotides essential for DNA and RNA synthesis. This pathway maintains a balanced nucleotide pool, preventing imbalances that could jeopardize genetic integrity and cellular function. Given the crucial role of nucleotides, their synthesis is tightly regulated to ensure proper cellular homeostasis.Purine BiosynthesisThe biosynthesis of purine nucleotides begins with ribose-5-phosphate, a...
