Canavan disease, a rare leukodystrophy, involves brain degeneration due to aspartoacylase deficiency. Early diagnosis in infants is crucial for managing this metabolic disorder.
Area of Science:
- Neuroscience
- Genetics
- Metabolic Disorders
Background:
- Canavan disease is an autosomal recessive leukodystrophy causing spongy degeneration of the brain.
- It stems from aspartoacylase deficiency, leading to N-acetyl aspartic acid accumulation.
Observation:
- A 10-month-old boy presented with developmental delay and megalencephaly after 4 months of age.
- Brain MRI revealed diffuse white matter degeneration.
Findings:
- Diagnosis was confirmed using nuclear magnetic resonance spectroscopy and gas chromatography-mass spectrometry.
- This case highlights the diagnostic utility of advanced imaging and biochemical tests.
Implications:
- Early identification of Canavan disease is vital for timely intervention.
- Understanding the genetic and metabolic basis aids in developing therapeutic strategies.

Allosteric Proteins-ATCase
Aspartate transcarbamoylase (ATCase) is a cytosolic enzyme that catalyzes the condensation of L-aspartate and carbamoyl phosphate to N-carbamoyl-L-aspartate. This reaction is the first step in pyrimidine biosynthesis. UTP and CTP, the end products of the pyrimidine synthesis pathway,...

Acute Pancreatitis I: Introduction
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:
