Abstract

The present invention relates to oligonucleotides that are capable of inducing expression of ubiquitin-protein ligase E3A (UBE3A) from the paternal allele in animal or human neurons. The oligonucleotides target the suppressor of the UBE3A paternal allele by hybridization to SNHG14 long non-coding RNA downstream of SNORD109B. The present invention further relates to pharmaceutical compositions and methods for treatment of Angelman syndrome.
