Mucopolysaccharidosis is a type of genetic metabolic disorder. It primarily affects the mucopolysaccharides, which is a form of complex carbohydrate that requires a certain enzyme so that the body can absorb it. If this enzyme is absent, the patient develops mucopolysaccharidosis. The most common symptoms of the condition are a roughening or coarsening of facial features, abnormal skeletal development, and enlargement of certain organs. The heart valves may also become damaged, and most patients have dwarfism, thick patches of skin, excessive hair all over the body, and frequent infections of the respiratory tract. Patients with mucopolysaccharidosis may experience considerable relief from the pain and discomfort associated with the condition.
