| Outline of Final Research Achievements |
Fukuyama type congenital muscular dystrophy (FCMD) is a second common, severe childhood muscular dystrophy in Japan. All patients have ancestral insertion of a SINE-VNTR-Alu retrotransposal element (SVA) into a causative gene fukutin. We show that aberrant mRNA splicing, induced by SVA exon-trapping caused FCMD (Taniguchi-Ikeda M et al, Nature 2011). Introduction of three cocktailed antisense oligonucleotides (AONs) targeting around these splice sites prevented pathogenic splicing in FCMD patient cells and model mice, and normalized protein production and functions of Fukutin as well as O-glycosylation of α-dystroglycan. Here we show the results of an optimization of the best, single AON for clinical trial. We tested if these AONs are effective in Central Nervous System (CNS). We could successfully deliver AONs to CNS in model mice.
