What if a genetic disease could be prevented before a baby is even born? Mitochondrial Replacement Therapy (MRT) is making that possibility a reality by helping families avoid inherited mitochondrial disorders.
In 2016, Dr. John J. Zhang and his team achieved the world’s first successful birth using Mitochondrial Replacement Therapy (MRT). The technique replaces faulty mitochondria in the mother’s egg with healthy mitochondria from a donor, preventing the transmission of mitochondrial diseases.
The baby inherits 99.8–99.9% of its DNA from its biological parents, while only 0.1–0.2% comes from the donor’s mitochondrial DNA, which contains 37 genes responsible for cellular energy production—not physical traits or personality.
MRT offers hope to families affected by mitochondrial diseases, which can severely impact the brain, heart, muscles, liver, and eyes.
MRT is a major milestone in reproductive medicine, giving families the chance to have healthy, genetically related children while reducing the risk of inherited mitochondrial disorders.
Should advanced genetic technologies like MRT be more widely used to prevent inherited diseases? Share your thoughts below!
