Muscular Dystrophy Statistics

GITNUXREPORT 2026

Muscular Dystrophy Statistics

One in 3,300 people worldwide are estimated to live with muscular dystrophy, yet Duchenne drives much of the urgency with up to 90% of patients facing respiratory complications, median loss of ambulation at about 12 years, and cardiac and breathing risks that can be delayed by early treatment. This page also connects the clinical reality to what is happening now, from the global gene therapy market reaching $2.2 billion in 2022 to the 2023 rare disease diagnostics and therapeutics spend, plus FDA accelerated and full approvals that changed DMD care timelines.

Muscular dystrophy affects about 1 in 3,300 people worldwide, but the ripple effects show up far beyond muscle weakness, from scoliosis to life changing respiratory decline. More than 90% of people with Duchenne muscular dystrophy die from respiratory complications, while half develop scoliosis and roughly 30% to 40% develop dilated cardiomyopathy. Alongside these clinical figures, the market and research landscape is also shifting, with the global gene therapy market reaching $2.2 billion in 2022 and registered muscular dystrophy trials rising 18% from 2019 to 2022.
