Genetic testing for the Ataxias is complicated, has different methodologies and needs to be carefully chosen in order to provide accurate information. NAF recommends that anyone having genetic testing work with a certified genetic counselor so that the appropriate genetic test is selected. NAF offers a no-cost genetic counseling and testing initiative for those at-risk for SCA1, 2, and 3. Read more about that below. General information about genetic counseling can be found at the National Society of Genetic Counselors website.
