Duchenne Muscular Dystrophy

Duchenne Muscular Dystrophy (DMD) is a severe genetic disorder characterized by progressive muscle degeneration and weakness, caused by mutations in the dystrophin gene on the X chromosome. It primarily affects boys, with symptoms typically appearing between ages 2-5 and progressing to loss of ambulation by age 12 and respiratory/cardiac complications by the late teens to twenties. For digital accessibility, DMD is significant because individuals retain cognitive function while progressively losing motor control, making them strong candidates for alternative input methods such as eye tracking, switch access, and voice control as the condition advances.
