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 test examines four specific variants—E285A, Y231X, 433-2A>G, and A305E—that are collectively associated with Canavan disease in individuals of Ashkenazi Jewish descent. Detecting carrier status or confirming an affected diagnosis relies on identifying these variants through a blood sample.
About Canavan Disease Carrier Test | Ashkenazi in Greenville
Canavan disease carrier testing focuses on a defined set of mutations rather than a broad sequencing approach.
The test targets four variants in the ASPA gene: E285A, Y231X, 433-2A>G, and A305E. These variants account for a substantial proportion of Canavan disease cases in the Ashkenazi Jewish population, where carrier frequency is higher than in the general population.
Canavan disease follows an autosomal recessive inheritance pattern. A carrier has one altered copy of the ASPA gene and typically does not show symptoms. If both partners are carriers, each pregnancy carries a one-in-four chance of producing an affected child.
Aspartoacylase deficiency leads to accumulation of N-acetylaspartic acid in the brain, which disrupts normal myelin development. This biochemical disturbance underlies the progressive neurological features seen in affected individuals. Testing for the four specified variants provides targeted information relevant to reproductive planning and diagnostic evaluation.
