摘要: Duchenne Muscular Dystrophy (DMD), a severe hereditary disease, affecting 1 boy out of 3500, mainly results from the deletion one or more exons leading to reading frame shift DMD gene that abrogates dystrophin protein synthesis. We used Cas9 Staphylococcus aureus (SaCas9) edit human gene. Pairs sgRNAs were meticulously chosen induce genomic not only restore but also produced with normally phased spectrin-like repeats. The formation repeats is usually obtained by skipping complete exons. This can however be in rare instances where exon/intron borders beginning and end (patient plus CRISPR-induced are at similar positions repeat. pairs sgRNAs, targeting 47 58 normal was restored 67 86% resulting hybrid myoblasts derived muscle biopsies 4 patients different exon deletions. restoration expression vivo heart del52hDMD/mdx.
