Key result
Among 108 DMD/BMD patients with 89 identified deletions, in-frame deletion of the hinge III region resulted in a milder phenotype compared with shorter deletions lacking this region.
Observational (n=108)
In-frame deletions of the hinge III region in the dystrophin gene correlate with a milder phenotype in Becker muscular dystrophy, informing potential gene therapy approaches.

Hinge III deletions may link to milder DMD/BMD phenotypes; leaves open targeted therapy implications pending validation.
Carsana et al. (2005) conducted an observational in Duchenne and Becker muscular dystrophy (n=108). In-frame deletion of the hinge III region vs. Shorter deletions that do not include the hinge III region was evaluated on Disease severity (phenotype). Among 108 DMD/BMD patients with 89 identified deletions, in-frame deletion of the hinge III region resulted in a milder phenotype compared with shorter deletions lacking this region.
