What are the best treatment options for a grandson with DMD who has an exons 3-17 duplication, out of frame?
Unfortunately, the currently available exon-skipping therapies (Exondys 51, Vyondys 53, Amondys 45, and Viltepso) target specific single exon deletions - exons 45, 51, and 53. These wouldn't be appropriate for your grandson's specific duplication mutation.
However, other treatment options may help manage his DMD:
Gene Therapy:
Delandistrogene moxeparvovec-rokl (Elevidys) is FDA-approved for people ages 4 and up with DMD. It works by prompting cells to produce dystrophin protein and has shown improvement in mobility. This may be an option regardless of the specific mutation type.
Symptom Management:
* Corticosteroids to help control symptoms and slow progression
* Mobility aids like walkers, braces, and wheelchairs as needed
* Physical and occupational therapy
* Surgery when appropriate
Clinical Trials:
Consider participating in clinical trials that may offer access to new treatments at little or no cost. Talk with your grandson's healthcare team about ongoing studies that might be suitable for his specific mutation.
Financial Support:
Organizations like The Assistance Fund and those listed through Parent Project Muscular Dystrophy (PPMD) may help with out-of-pocket costs for medical care, home modifications, assistive devices, and healthcare travel.
Regarding best places to live, the search results don't address geographic considerations, but connecting with specialized DMD care centers and support networks would be beneficial wherever you are.
