Order Canavan Disease Carrier Test | AshkenaziCanavan disease is a rare inherited neurological disorder caused by variants in the ASPA gene, which encodes the enzyme aspartoacylase. This carrier test examines four specific ASPA mutations—E285A, Y231X, 433-2A>G, and A305E—that are observed with increased frequency in individuals of Ashkenazi Jewish ancestry.
About Canavan Disease Carrier Test | Ashkenazi in Greer
Canavan disease follows an autosomal recessive pattern of inheritance, meaning that an affected child inherits a pathogenic variant from each parent.
The ASPA gene provides instructions for producing aspartoacylase, an enzyme that breaks down N-acetylaspartic acid (NAA) in the brain. When ASPA function is reduced or absent, NAA accumulates and contributes to the destruction of myelin-producing cells, leading to the progressive neurological features associated with Canavan disease.
Carriers of a single ASPA variant typically do not develop symptoms, because one functioning copy of the gene is sufficient for normal enzyme activity. Two carriers have a one-in-four chance with each pregnancy of having an affected child, a one-in-two chance of having a carrier child, and a one-in-four chance of having a child who inherits neither variant.
This test detects four ASPA mutations: E285A, Y231X, 433-2A>G, and A305E. These variants account for a substantial proportion of Canavan disease alleles in the Ashkenazi Jewish population, though testing is not exhaustive and other rare variants would not be identified by this panel.
