8C70.0/G71.0 Becker muscular dystrophy



Becker muscular dystrophy is an X-linked form of muscular dystrophy caused by a mutation of the gene encoding the dystrophin protein.


Becker muscular dystrophy is usually diagnosed through a combination of physical exams, family history, and genetic testing. Physical exams usually reveal muscle weakness and wasting, as well as muscle enlargement (hypertrophy) in the calves.

Differential diagnosis

Becker muscular dystrophy can be differentiated from other forms of muscular dystrophy by genetic testing.


Treatment for Becker muscular dystrophy is focused on managing symptoms and preventing complications. Options may include physical therapy, occupational therapy, bracing, and medications to manage pain and muscle spasms.


The prognosis for Becker muscular dystrophy is variable and depends on severity of the condition. Most people with Becker muscular dystrophy can expect to have a normal lifespan, but may experience progressive muscle weakness and need assistance with activities of daily living.
