University of Rochester -- Boys show signs of Duchenne Muscular Dystrophy (DMD) for 2 ½ years before they obtain a diagnosis and disease-specific treatment, about the same length of delay children have endured for the past 20 years despite advances in genetic testing and treatment. A simple and inexpensive blood test for any boy with symptoms and signs of motor delays and abnormalities could speed up the process while pilot studies on newborn screening are conducted.
