There are distinct relationships between frataxin levels and severity of disease. A. We confirm the suggested inverse relationship between patient age of onset and GAA repeat length of the shorter allele (p<0.001). B. Measured frataxin levels inversely correlates with GAA repeat length, suggesting that the assay is useful for assessing severity of disease in buccal cells (p<0.001). C. Age of onset correlates directly with measured frataxin levels (p<0.001).
