Does DMD have abnormal chromosome numbers?

Duchenne Muscular Dystrophy (DMD) itself is not characterized by abnormal chromosome numbers. Instead, it is caused by mutations in the dystrophin gene located on the X chromosome. While individuals with DMD may have normal chromosome counts, the specific mutation in the dystrophin gene leads to the disease's characteristic muscle degeneration. Therefore, the chromosomal makeup is typically normal, but the genetic mutation is what causes the disorder.
