BY KERRY LYNN MACINTOSH* INTRODUCTION All human beings have mitochondria within their cells that produce energy.1 Most of us inherit healthy mitochondria through the eggs of our mothers,2 but some of us are not so lucky. Mutations in mitochondrial DNA (mtDNA) can cause these tiny organelles to function improperly and disrupt tissues that require a lot of energy, like the brain, kidney, liver, heart, muscle, and central nervous system.3 For example, a specific mtDNA mutation induces Leigh syndrome, a condition in which seizures and respiratory failure lead to decline in mental and motor skills, disabil- ity, and death.4 Mitochondrial replacement therapy (MRT) offers a solution to this problem.
