Degeneración esponjosa del cerebro; Deficiencia de aspartoacilasa
Es una enfermedad hereditaria que afecta la descomposición y uso (metabolismo) del ácido aspártico.
La enfermedad de Canavan se transmite (hereda) de padres a hijos y es más común entre los judíos asquenacíes que en la población general.
La falta de la enzima aspartoacilasa lleva a una acumulación de material llamado ácido-N-acetilaspártico en el cerebro. Esto ocasiona la descomposición (deterioro) de la sustancia blanca del cerebro.
