GAA‐FGF14 Expansions and CACNA1A Variants: Phenotypic Overlap and Diagnostic Implications

Background An intronic (GAA)•(TTC) repeat expansion in FGF14 was recently identified as the cause of spinocerebellar ataxia 27B (SCA27B), a disorder presenting with both chronic cerebellar ataxia and episodic symptoms. The phenotype of SCA27B overlaps with that of CACNA1A spectrum disorders. Objecti...
