Abstract

We discovered intronic mutations in two episodic ataxia type 2 (EA2) families: a four-nucleotide GAGT deletion at IVS41+(3-6) and a single nucleotide insertion (insT) at IVS24+3. We expressed minigenes harboring the mutations in cell lines to demonstrate exon skipping from the deletion mutation and the activation of a cryptic splice donor site from the insertion mutation. The identification of these disease-causing mutations expands the spectrum of EA2 mutations and emphasizes the importance of intronic sequences in regulating gene expression.
