The Brain in Duchenne Muscular Dystrophy

By the early 1990s, researchers began to see more than they had expected. The dystrophin gene wasn't just a muscle protein gene. There was also a brain form of dystrophin, made from the same gene, but in a slightly different way.Not surprisingly, scientists began to speculate that, if this brain protein were also flawed in  Duchenne muscular dystrophy  (DMD), it might account for the cognitive problems seen in the disease. And, if different people had different flaws in the same gene, it might account for some of the variation seen with these problems.
