WHAT CAUSES MUSCLE WEAKNESS?
Most muscle weakness is caused by defects in the enzymes (Agnis) that control chemical reactions used to breakdown food. Enzyme defects are caused by flaws in the genes that govern production of the enzymes. A gene is arecipe or set of instructions for making a protein, such as an enzyme. A defect in the gene may cause the protein to be made incorrectly or not at all, leading to deficiency in the amount of that enzyme. Genes are passed from parents to children. Therefore genetic defects can be inherited. In normal metabolism, food provides fuel thats processed inside the cells, producing energy (ATP) for muscle contraction and other cellular functions. In metabolic myopathies, missing enzymes prevent mitochondria from properly processing fuel, and no energy is produced for muscle function. Muscular dystrophy refers to a group of genetic diseases characterized by progressive weakness and degeneration of the skeletal or voluntary muscles which control body movement. The muscles of the he
