Becker muscular dystrophy (BMD) is an inherited condition that primarily affects males and causes progressive weakness and wasting of the skeletal and cardiac (heart) muscles.[1][2] The age of onset and rate of progression can vary among affected people. Muscle weakness usually becomes apparent between the ages of 5 and 15. In some cases, heart involvement (cardiomyopathy) is the first sign.[2] BMD is caused by a mutation in the DMD gene and is inherited in an X-linked recessive manner. BMD is very similar to Duchenne muscular dystrophy, except that symptoms begin later and progress at a slower rate.[1] There is no cure for this condition, and treatment aims to relieve symptoms to help quality of life.[3] People with BMD may survive into their 40s or beyond.[1]
