In the United States, only two clinical labs (University of Chicago & Variantyx) can test for the GAA repeat expansion in the gene (FGF14) that causes SCA27B. As we gather better information on the labs offering testing in other countries, we will post them here.

The SCA27B test (repeat GAA expansion in FGF14) is now also available through Variantyx. Your neurologist or genetic counselor can order your test here:

Your provider will need to set up a simple online account with a UN/PW to order your genetic test through the online portal. Variantyx will test for the repeat expansion causing SCA27B with a panel of other hereditary ataxias. Your provider will determine what test panel is best for you.
