Abstract: The present invention relates to repeat expansion disorders. Missplicing is understood to be a general phenomenon that can occur in repeat expansion disorders wherein the DNA and/or RNA sequence of repeat sequences in expanded repeat disorders can cause such aberrant transcription and/or aberrant splicing, resulting in misspliced transcripts, i.e. transcripts that do not have the putative splicing as observed e.g. for corresponding non-diseased genes. Such misspliced transcripts can be in particular associated with disease. Hence, the current invention now provides means and methods for targeting misspliced transcripts which is highly useful for the treatment of expanded repeat disorders.

Abstract: The current invention relates to gene therapy approaches for the treatment of SCA3, in particular RNAi based gene therapy approaches utilizing a total knockdown approach. The inventors provide for selected target regions and/or target sequences for which highly efficient knockdown of the ATXN3 gene expression can be advantegeously obtained in human neuronal cells and in mouse models relevant for SCA3.

Abstract: The invention relates to means and methods for removing a proteolytic cleavage site from a protein comprising providing a cell that expresses pre-mRNA encoding the protein with an anti-sense oligonucleotide that induces skipping of the exonic sequence that encodes the proteolytic cleavage site, the method further comprising allowing translation of mRNA produced from the pre-mRNA.

Abstract: Described are methods for removing a proteolytic cleavage site, the HCHWA-D mutation or the amino acids encoded by a trinucleotide repeat expansion from a protein comprising providing a cell that expresses pre-mRNA encoding the protein with an anti-sense oligonucleotide that induces skipping of the exonic sequence that comprises the proteolytic cleavage site, HCHWA-D mutation or trinucleotide repeat expansion, respectively, the method further comprising allowing translation of mRNA produced from the pre-mRNA.
