Question

Quizplus · Accepted Answer

Duchenne's muscular dystrophy (DMD) is characterized by muscle weakness that begins in early childhood, typically between 2 and 5 years of age. One of the earliest signs is difficulty climbing stairs or standing up from a seated or lying position.

Answer: C 
 DMD is a progressive disorder that primarily affects skeletal muscles, including those in the legs. Muscle weakness and wasting (atrophy) can be seen in the legs of a toddler with DMD.

Answers B and D are incorrect. DMD affects multiple muscle groups throughout the body, not just the legs and pelvis. Carrier status can be detected through genetic testing.
