DMD stands for which condition?

• A. Duchenne Muscular Dystrophy
• B. Duchenne Myopathy Disorder
• C. Duchenne Muscle Degeneration
• D. Duchenne Dystrophic Myopathy

Answer: (A)

The main idea is recognizing what DMD stands for in clinical naming. DMD expands to Duchenne Muscular Dystrophy, a severe X-linked muscular dystrophy caused by mutations in the dystrophin gene, which leads to little or no dystrophin protein. Dystrophin helps stabilize muscle cell membranes during contraction, so without it, muscles incur damage over time and weaken progressively. This condition typically begins in early childhood with proximal muscle weakness, difficulty running or climbing stairs, a characteristic Gowers maneuver, and calf enlargement from fibrofatty replacement. The reason this is the best answer is that Duchenne Muscular Dystrophy is the standard, widely accepted name for the disease abbreviated as DMD. The other phrases—Duchenne Myopathy Disorder, Duchenne Muscle Degeneration, or Duchenne Dystrophic Myopathy—do not reflect the established clinical name for this condition.
