Her paroxysmal dystonia is likely due to her mutation in CACNA1A, as it is sometimes seen during episodes of ataxia in EA2 [9], there are other case reports of CACNA1A mutations being associated with dystonia, and CACNA1A knockout mice (CaV2.1−/−) exhibit dystonia and cerebellar atrophy [3]. This evidence concerns the gene CACNA1A and Dystonia.
