Which term denotes a genetic disease affecting mainly muscles?

• A. Diabetes Mellitus
• B. Hepatitis
• C. Cystic Fibrosis
• D. Muscular Dystrophy

Answer: (D)

Muscular dystrophy describes inherited disorders in which muscles progressively weaken and waste away because of genetic mutations that disrupt the proteins in muscle fibers (for example, dystrophin in some forms). This makes the condition primarily about muscles and inherited genetic cause, which is why it fits best. Diabetes mellitus is a metabolic disorder affecting insulin and glucose regulation; hepatitis is liver inflammation often due to infection; cystic fibrosis is a genetic disease mainly impacting the lungs and digestive system. So the term that best matches a genetic disease affecting mainly muscles is muscular dystrophy.
