Abstract
Molecules are provided for inducing or facilitating exon skipping in forming spliced mRNA products from pre-mRNA molecules in cells. The molecules may be provided directly as oligonucleotides or expression products of vectors that are administered to a subject. High rates of skipping can be achieved. High rates of skipping reduce the severity of a disease like Duchene Muscular Dystrophy so that the disease is more like Becker Muscular Dystrophy. This is a severe reduction in symptom severity and mortality.
Claims10
An oligomer for ameliorating DMD, the oligomer comprising at least 25 contiguous bases of a base sequence selected from the group consisting of:
- a) CAG XXX GCC GCX GCC CAA XGC CAX CCX GGA (SEQ ID NO:
- 4);
- b) XXG CCG CXG CCC AAX GCC AXC CXG GAG XXC (SEQ ID NO:
- 5);
- wherein X=U or T, wherein the oligomer's base sequence can vary from the above sequence at up to two base positions, and wherein the molecule can bind to a target site to cause exon skipping in an exon of the dystrophin gene.
