Muscular dystrophies are a group of genetic conditions characterized by progressive muscle weakness and wasting (atrophy). The Duchenne and Becker types of muscular dystrophy are two related conditions that primarily affect skeletal muscles, which are used for movement, and heart (cardiac) muscle.These forms of muscular dystrophy occur almost exclusively in males.he Duchenne and Becker types of muscular dystrophy are two related conditions that primarily affect skeletal muscles, which are used for movement, and heart (cardiac) muscle.
Different types of muscular dystrophy affect specific groups of muscles, have a specific age when signs and symptoms are first seen, vary in how severe they can be, and are caused by imperfections in different genes. Muscular dystrophy can run in the family, or a person might be the first one in their family to have the condition. Muscular dystrophy is rare, and there is not a lot of data on how many people are affected by the condition. Much of the information comes from outside the United States. CDC scientists are working to estimate the number of people with each type of muscular dystrophy in the United States.
