METHODS AND COMPOSITIONS FOR MITOCHONDRIAL REPLACEMENT THERAPY
The invention features methods, kits, and compositions for mitochondrial replacement in the treatment of disorders arising from mitochondrial dysfunction. The invention also features methods of diagnosing neuropsychiatric (e.g., bipolar disorder) and neurodegenerative disorders based on mitochondrial structural abnormalities.
