Becker Muscular Dystrophy (BMD): BMD is a dystrophinopathy caused by mutations in the dystrophin gene that result in a truncated, partially functional dystrophin protein. The truncated dystrophin protein results in sarcolemmal instability and progressive muscle disease. BMD is less common than DMD and occurs in between 3-6/100,000 male births. BMD patient’s exhibit symptoms between 8-15 years of age and can exhibit dilated cardiomyopathy and reduced life expectancy. There are currently no definitive therapies for BMD and only steroid therapy and palliative care are available.
