Definition of Muscular dystrophy, Becker

Medically reviewed by Dr. Otari Nergadze, Neurosurgeon | Updated: January 2026

Muscular dystrophy, Becker: A form of muscular dystrophy (MD) that is similar to Duchenne MD but milder. Patients with Becker MD produce a little of the key protein, dystrophin, whereas those with Duchenne make none. Progression of Becker MD is slower and symptoms tend to appear later than progression of Duchenne MD. Both Becker and Duchenne MD result from mutations in the gene on the X chromosome that encodes dystrophin.
