  • Canavan disease (CD) is a severe, lethal leukodystrophy caused by deficiency in aspartoacylase (ASPA), which hydrolyzes N-acetylaspartate (NAA). In the brains of CD patients, NAA accumulates to high millimolar concentrations. The pathology of the disease is characterized by loss of oligodendrocytes

  • A 3-year-old boy was admitted with psychomotor delay, spasticity, progressive visual loss, nystagmus, macrocephaly, and epileptic seizures for diagnostics. Cranial magnetic resonance imaging (MRI) revealed leukodystrophy and multicystic changes. Urine excretion of N-acetylaspartic acid was grossly i
