Duchenne Muscular Dystrophy
Definition: One of nine types of muscular dystrophy, a group of genetic, degenerative diseases primarily affecting voluntary muscles.
Cause: An absence of dystrophin, a protein that helps keep muscle cells intact.
Onset: Early childhood - about 2 to 6 years.
Symptoms: Generalized weakness and muscle wasting first affecting the muscles of the hips, pelvic area, thighs and shoulders. Calves are often enlarged.
Progression: DMD eventually affects all voluntary muscles, and the heart and breathing muscles. Survival is rare beyond the early 30s.
Inheritance: X-linked recessive. DMD primarily affects boys, who inherit the disease through their mothers. Women can be carriers of DMD but usually exhibit no symptoms.
