Answers
Answer:
Muscular dystrophy is group of genetic disorders leading to the degeneration and weakening of skeletal muscles.
Causes:
The muscular dystrophies are mainly inherited diseases. However different inheritance patterns are followed by different types of muscular dystrophies. The most common cause of the disease is the mutation in the dystrophin gene and nutritional defects at the prenatal stage. The defects in this gene results in the formation of non functional dystropin protein found in the muscle fibre membrane. This protein is essential for mechanical stabilisation of muscle fibre and regulation of calcium level necessary for the function of muscles. Thus, results in the progressive weakness and loss of muscle mass.
Answer:
==> In most cases, muscular dystrophy (MD) runs in families. It usually develops after inheriting a faulty gene from one or both parents. MD is caused by mutations (alterations) in the genes responsible for healthy muscle structure and function.
==> Signs and symptoms, which typically appear in early childhood, might include:
Frequent falls
Difficulty rising from a lying or sitting position
Trouble running and jumping
Waddling gait
Walking on the toes
Large calf muscles
Muscle pain and stiffness
Learning disabilities
Delayed growth
