For the first time, scientists say they have reached into the genome of a severely ill child and rewritten the unique misspelling in his DNA.\u00a0<\/p>\n

The results, published<\/a> in the New England Journal of Medicine on Thursday, are a landmark in the 50-year quest to read and repair the code of life. The boy, a now 9.5-month-old named KJ, was diagnosed days after birth with an ultra-rare disease that impairs his liver\u2019s ability to process ammonia, which can build up and cause permanent brain damage or death.\u00a0<\/p>\n

KJ had been living in the hospital, waiting until he was old enough to receive a liver transplant. Instead, at 6 months, doctors administered the first dose of the gene editing treatment. They have since been able to loosen a strict low-protein diet and reduce his daily ammonia-lowering medications by half.\u00a0<\/p>\n
