Overview
Historical Perspective
- Canavan disease was first described in 1931 by an American neuropathologist, Myrtelle Canavan.[1]
- She wrote a case-study in 1931 of a child who died at sixteen-month of age and was found to have cerebral spongy degenerative changes of the central nervous system.[1]
- The disease was later named after Myrtelle Canavan.
Classification
- There is no established system for the classification of Canavan disease.
- Canavan disease is categorized as a leukodystrophy.[2]
Pathophysiology
- Canavan disease is a rare inherited disorder following an autosomal recessive pattern of inheritance. [3]
- It is caused by a deficiency of enzyme aspartoacylase.
- Aspartoacylase is responsible for breakdown of N-acetyl aspartate (NAA) into aspartic acid and acetate.
- Decreased level of aspartoacylase results in accumulation of N-acetyl aspartate (NAA) in the brain causing abnormal myelination and progressive cerebral spongy degeneration.[3]
