Gene Therapy Leads to Long-Term Benefits in Dog Model of Devastating Childhood Disease

Researchers who previously showed that a gene therapy treatment could save the lives of dogs with a deadly disease called myotubular myopathy—a type of muscular dystrophy that affects the skeletal muscles—have found that the therapy is long-lasting. The results support a clinical trial in patients.

Myotubular myopathy is estimated to affect 1 in 50,000 male births, and boys born with the condition often die in the first year of life.

In this latest study, investigators found that replacing the MTM1 gene, which is mutated in patients, leads to sustained preservation of muscle strength and neurologic function in dogs over 4 years.

“This regenerative technology, termed AAV gene transfer, provided long-lasting benefit to the entire musculature of affected dogs that would have otherwise perished, extending a healthy lifespan for more than 4 years,” said Dr. Martin Childers, senior author of the Muscle & Nerve study and a UW Medicine researcher in Seattle.

About Journal

Muscle & Nerve is an international and interdisciplinary publication of original contributions, in both health and disease, concerning studies of the muscle, the neuromuscular junction, the peripheral motor, sensory and autonomic neurons, and the central nervous system where the behavior of the peripheral nervous system is clarified.
