Canavan disease, or Canavan–Van Bogaert–Bertrand disease, is a rare and fatal autosomal recessive [1] degenerative disease that causes progressive damage to nerve cells and loss of white matter in the brain. [2] It is one of the most common degenerative cerebral diseases of infancy. [3]
Canavan's disease, Van Bogaert-Bertrand type, Aspartoacylase deficiency: Magnetic resonance imaging scans showing dysmyelination, a possible indicator of Canavan's disease: Specialty: Neurology: Symptoms: Hypotonia, macrocephaly, loss of vision, motor reflex defects, difficulties in breathing and swallowing: Usual onset: 3-6 months of age ...
While the disease is fatal, the age of onset is a key factor, as infants have a typical life expectancy of 2–8 years, while adults typically live more than a decade after onset. Treatment options are limited, although hematopoietic stem cell transplantations using bone marrow or cord blood seem to help in certain leukodystrophy types, while ...

Enzyme replacement therapy is available to treat mainly Fabry disease and Gaucher disease, and people with these types of sphingolipidoses may live well into adulthood. The other types are generally fatal by age 1 to 5 years for infantile forms, but progression may be mild for juvenile- or adult-onset forms.
Aminoacylase 2 deficiency - also known as Canavan's disease - is another rare disease caused by a mutation in the ASPA gene (on chromosome 17) that leads to a deficiency in the enzyme aminoacylase 2. Aminoacylase 2 is known for the fact that it can hydrolyze N-acetylaspartate while aminoacylase 1 cannot. [17]
The plaintiffs in this case were a group of parents of children who had Canavan disease and three non-profit organizations who developed a confidential Canavan disease registry and database. [1] The parents provided their children's tissue for research on the disease and the non-profit groups aided in the identification of other affected ...
Clinical progression of the disease is variable, with lung transplantation required in severe cases. Susceptibility to infections can be drastically reduced by an early diagnosis. Treatment with various chest physiotherapy techniques has been observed to reduce the incidence of lung infection and to slow the progression of bronchiectasis ...
