Surprising Findings Related to Myotonic Muscular Dystrophy
University of Virginia Health SystemNew research from the University of Virginia Health System shows that, in cases of Type 1 myotonic muscular dystrophy (DM1), a well known heart protein does several surprising things. DM1 is the most common form of muscular dystrophy in adults and affects approximately 40,000 adults and children in the U.S. The researchers were surprised to find that mice and individuals with DM1 actually overproduce the protein, NKX2-5, yet experience the same kind of heart problems associated with too little of it.
