Mitochondrial diseases can affect any organ in the body and at any age.
Mitochondrial diseases are severely debilitating, often fatal and characteristically complex in nature. They are inherited through the mother, but can also be inherited from either parent. They can also be sporadic or induced by the environment. In the United States, more than 50 million adults suffer from diseases in which mitochondrial dysfunction is involved. Mitochondrial dysfunction is found in diseases as diverse as cancer, infertility, diabetes, heart diseases, blindness deafness, kidney disease, liver disease, stroke, migraine, and the toxicity of HIV and other drugs.
