However, in the patients with SCA, we did find a significant correlation between RL and LL stiffness and serum levels of Tg (r = −0.439 RL and r = −0.484 LL, P = 0.021), and levels of fT3 (r = −0.463 RL and r = −0.386 LL, P = 0.012) (Figure 3). This evidence concerns the gene TG and autosomal dominant cerebellar ataxia.
