The present invention provides a method for the treatment of autosomal dominant Catecholaminergic Polymorphic Ventricular Tachycardia associated with mutations in the cardiac ryanodine receptor type 2 (RYR2) gene, by the use of an AAV mediated RNA interference approach to induce allele specific silencing of mutant mRNA.

Recent advancements in LNA oligonucleotides include the use of amine linkers to link an LNA antisense oligonucleotide to a conjugate group. For example please see WO2014/I18267. The present invention originates from the identification of a problem when de-protecting LNA oligonucleotides which comprise an aliphatic amine group and DMF protected LNA G nucleoside, which results in the production of a +28 Da impurity. This problem is solved by using acyl protection groups on the exocyclic nitrogen of the LNA-G residue, rather than the standard DMF protection group.
