Clinical analysis highlights effectiveness of mitochondrial therapies in disease prevention, suggesting potential but uncertain reliability.
Mitochondrial replacement therapies (MRTs) have been proposed as a means of avoiding the transmission of pathogenic mitochondrial DNA (mtDNA) mutations from mother to child. While clinical cases using this groundbreaking strategy have now been reported for the two principal MRT methods-pronuclear transfer and maternal spindle transfer-recent data continues to raise questions about the reliability of these approaches for disease prevention.
