What this test is

The Canavan disease carrier test is a genetic blood test that looks for four specific changes in the ASPA gene: E285A, Y231X, 433-2A>G, and A305E. It can show if a person carries one copy of a change, which usually causes no symptoms, or if a person has two copies, which is associated with the disease. This test is often offered to people with Ashkenazi Jewish ancestry because these changes are more common in that group.

What it measures

  • E285A — one of the four ASPA gene changes linked to Canavan disease
  • Y231X — one of the four ASPA gene changes linked to Canavan disease
  • 433-2A>G — one of the four ASPA gene changes linked to Canavan disease
  • A305E — one of the four ASPA gene changes linked to Canavan disease

What the test involves

A small sample of blood is collected, usually from a vein in the arm, during a standard blood draw. The sample is then sent to a laboratory for genetic analysis.

Why it is often ordered

A clinician may order this test to find out if a person carries a gene change that could be passed on to children. It is often considered when there is a family history of Canavan disease or when someone wants information for family planning.

Preparation

No special preparation is usually needed, but you should follow the instructions given by the collection site or laboratory. If you have questions about fasting or medications, ask the lab before your appointment.

How results are reported

Results are reported as positive or negative for each of the four gene changes, and a genetic counselor can help explain what they mean. Reference ranges and reporting methods can vary by laboratory, so always discuss your results with your healthcare provider.

Before you go

  • Whether any special preparation is needed before the blood draw
  • How long results typically take at that laboratory
  • Whether genetic counseling is available to help interpret results
