N-Acetylaspartic Aciduria in Canavan Disease: Another Proof in Two Infants

Abstract

Increased amounts of urinary N-acetyl-aspartic acid was found in two infants with biopsy proven Canavan disease. The aspartoacylase assay is a new tool for determining both the prenatal and antenatal diagnosis of Canavan disease. This assay should be screened in patients with early onset of psychomotor deterioration, macrocephaly, spasticity/hypotonia and white matter hyperleucency at CT scan.
