Upregulation of N-acetylaspartic acid resulting nitric oxide toxicity induces aspartoacylase mutations and protein interaction to cause pathophysiology seen in Canavan disease.

Abstract excerpt

Aspartoacylase (ASPA) converts N-acetylaspartic acid into aspartate and acetate. In Canavan disease (CD), N-acetylaspartic acid (NAA) is found to be increased and over 65 mutations including IVS4+1 G → T, deletion of introns and exons have been reported in the ASPA gene. These changes lead to severe form or mild form of CD. The present study was aimed to understand mechanism in the cause of mutations in ASPA and...
