SMN2 ELEMENT 1 ANTISENSE COMPOSITIONS AND METHODS AND USES THEREOF

摘要

The invention provides methods and compositions for treatment of spinal muscular atrophy (SMA). In one aspect of the invention, a series of compositions comprising an antisense oligonucleotide targeting the Element 1 site on the SMN2 pre-mRNA and a Morpholino backbone is disclosed. In another aspect of the invention, a method of treating SMA patients by modulating the splicing of SMN2 pre-mRNA to increase the amount of full-length SMN is disclosed. Certain embodiments of the inventive method comprise administering an E1-targeting antisense oligonucleotide, such as Morpholino based antisense oligonucleotide, to a SMA subject.
