Detailed explanation-1: -What is muscular dystrophy? Muscular dystrophy (MD) refers to a group of more than 30 genetic diseases that cause progressive weakness and degeneration of skeletal muscles used during voluntary movement. These disorders vary in age of onset, severity, and pattern of affected muscles.
Detailed explanation-2: -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.
Detailed explanation-3: -MD is caused by changes (mutations) in the genes responsible for the structure and functioning of a person’s muscles. The mutations cause changes in the muscle fibres that interfere with the muscles’ ability to function. Over time, this causes increasing disability.
Detailed explanation-4: -Myasthenia gravis is a chronic autoimmune, neuromuscular disease that causes weakness in the skeletal muscles (the muscles that connect to your bones and contract to allow body movement in the arms and legs, and allow for breathing).
