2.1.1.2 Becker muscle dystrophy (BMD)

BMD is a milder form of muscular dystrophy characterized by skeletal muscle weakness with a later onset and a preservation of the gait for a longer period (age of 40–50 years) [25]. The patients present usually with high serum CK concentration, calf muscle hypertrophy, muscle cramps, myalgia, or with muscle weakness in the pelvic and shoulder girdles [26]. Cardiomyopathy is a common complication of BMD, the mean age of diagnosis being around 14, 6 years [28]. Heart failure represents the most common cause of death in BMD, at an age of mid-40s [23, 24].
