Differences in the DNA within the mitochondria, the energy-producing structures within cells, can determine the severity and progression of heart disease caused by a nuclear DNA mutation. When combined with a mutation in nuclear DNA in animals, one mitochondrial DNA variant greatly worsened heart disease, while a different variant had a protective effect.
