Dystrophin is hypothesized to be involved in the … WebDuchenne muscular dystrophy is a rare, genetic condition that is characterized by progressive muscle damage and weakness. Sometimes shortened to DMD or Duchenne, this rare disease is caused by a genetic mutation that prevents the body from producing a protein called dystrophin. Dystrophin acts like a shock absorber when muscles contract.
