ASPA

Catalyzes the deacetylation of N-acetylaspartic acid (NAA) to produce acetate and L-aspartate. NAA occurs in high concentration in brain and its hydrolysis NAA plays a significant part in the maintenance of intact white matter. In other tissues it acts as a scavenger of NAA from body fluids.

Canavan disease

CAND

A rare neurodegenerative condition of infancy or childhood characterized by white matter vacuolization and demyelination that gives rise to a spongy appearance.

Belongs to the AspA/AstE family. Aspartoacylase subfamily.

Brain white matter, skeletal muscle, kidney, adrenal glands, lung and liver.
