In a groundbreaking moment for medicine, doctors in the United States have successfully changed the DNA of a baby girl to treat a life-threatening genetic disorder. The baby, who was born with a severe condition called Artemis-SCID, could not fight infections because her immune system did not work. Without treatment, babies with this disease often die within the first two years of life.

To save her, doctors used a special method called base editing. This new technique allows scientists to fix a single letter in the DNA without cutting it. They took bone marrow cells from the baby, edited the faulty gene in a lab, and then put the healthy cells back into her body. This was the first time base editing was used to treat a person directly for a rare inherited disorder.

The baby, now one year old, is doing well and has started building a healthy immune system. Experts say this success could help many more children in the future who are born with similar serious diseases. The treatment was developed by researchers at Boston Children’s Hospital and Great Ormond Street Hospital in the UK, offering hope for many families around the world.
