TS-000513 — Dystrophinopathies are a group of disorders caused by mutations in the DMD gene which codes for dystrophin, the vital, muscle-specific structural protein. Currently, there is no cure for muscular dystrophy, and patients only rely on palliative care options. Our gene therapy researchers at Nationwide Children’s Hospital have developed an AAV-mediated gene editing method for correcting deleterious DMD mutations in affected patients. This therapy uses a homology-independent targeted integration (HITI) to replace any missing or aberrant exons in affected patients; therefore, correcting the underlying cause of DMD. This therapy will be developed to stop the progression of muscle wasting and fibrosis in individuals with DMD mutations that result in muscular dystrophy via permanent correct of the underlying cause within muscle tissue by replacing missing or aberrant exons using HITI. Advantages By developing AAV-Mediated HITI gene editing for correction of diverse DMD mutations in patients with muscular dystrophy, we can potentially cure BMD and DMD patients. These patients currently have no palliative care options. Our compositions of matter for this approach (i.e. genomic target region, guide-RNA sequences, donor DNA sequences) are new.

TS-000308 — Absence of the dystrophin protein leads to the severe muscle disorder Duchenne Muscular Dystrophy (DMD). Nearly asymptomatic patients have been identified to produce a functional N-terminal truncated dystrophin protein. Gene therapy experts at Nationwide Children's Hospital are developing a U7-snRNA exon skipping strategy to facilitate expression of a truncated dystrophin protein for patients carrying mutations within exon 6 to 9 of the DMD gene, rendering their dystrophin nonfunctional. Our experts have effectively skipped exon 8 in patient-derived cell lines and in turn produced a functional truncated dystrophin protein product.

TS-000127 — Putative cytidine monophosphate-N-acetylneuraminic acid hydroxylase-like protein is an enzyme that in humans is encoded by the CMAH gene. A new CMAH-Deficient mouse model for DMD-related research has been created. The CMAH-Deficient mouse model mimics the human disease better than the current standard model thus providing a model for DMD that facilitate translational research to be more relevant to issues affecting the human disease.
