FGF14 and Dysarthria: Comparison of all clinical features in the two cohorts revealed significantly less frequent permanent cerebellar dysarthria (2/17; 12% vs 14/26; 54%; Fisher’s exact test p=0.009) and non-significantly more frequent episodic symptoms (10/17; 59% vs 7/26; 27%; Fisher’s exact test p=0.06) in GAA-FGF14-positive compared with GAA-FGF14-negative patients.
