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]
The first case of spongy degeneration of the CNS was reported in 1928 by Globus and Strauss, [42] who designated the case as Schilder's disease, a term for diffuse myelinoclastic sclerosis. [43] [44] [45] In 1931, Canavan reported a case where the megalencephaly of brain degeneration is different from that caused by a tumour. [46]
Canavan disease is a less-studied type of leukodystrophy that, like MLD and Krabbe disease, is also inherited in an autosomal recessive pattern. It is due to a mutation in the ASPA gene that encodes aspartoacylase , an enzyme needed to metabolize N-acetyl-L-aspartate (NAA).
Glutaric aciduria type 1 (GA1): An autosomal recessive disease, GA1 is due to glutaryl-coenzyme A dehydrogenase deficiency. Abnormalities are seen in the basal ganglia and dentate nucleus. [12] Canavan's disease: Canavan's disease is a white matter disease due to aspartoacylase deficiency. The dentate nucleus is not affected until late in ...
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 ...
Canavan disease is a rare autosomal recessive disorder that causes spongy degeneration of the white matter in the brain and severe psychomotor retardation, usually leading to death at a young age. [ 12 ] [ 20 ] The loss of aspartoacylase activity leads to the buildup of N-acetyl-L-aspartate in the brain and an increase in urine concentration by ...
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.
[clarification needed] It is very hard to map the spread of the disease due to the difficulty of identifying individual strains of the prions. This means that, if animals at one farm begin to show the disease after an outbreak on a nearby farm, it is very difficult to determine whether it is the same strain affecting both herds—suggesting ...
