Biochemical diagnosis of Canavan disease.
Canavan disease (CD) is a rare autosomal recessive disorder characterized by macrocephaly and progressive leukodystrophy. Up to now biopsy or necropsy were required to define the diagnosis. Recently the disease has been related to N-acetylaspartic aciduria and deficiency of aspartoacylase, an enzyme possibly involved in the myelin synthesis. These biochemical findings have provided a diagnostic marker for the disease. We report a new case of infantile CD in which the demonstration of N-acetylaspartic aciduria and a marked deficiency of aspartoacylase activity confirmed the diagnosis.
