Mitochondrial donors should be carefully selected to avoid transmission of harmful mutations, outlines a new report. Mitochondrial replacement therapy offers hope for women genetically predisposed to pass on mutant mitochondria, the tiny powerhouses inside nearly every cell of the body. Mitochondrial DNA is passed only from mothers to their children. Mutations can cause a range of potentially fatal disorders affecting organs with high-energy demands such as the heart, muscle and brain.
