Genetic therapy has reached a new milestone with one-year-old Layla seemingly cured of childhood leukemia. Layla was recently diagnosed with incurable leukemia and as a last ditch effort her parents and doctors received permission to try an experimental gene therapy treatment. Donor immune cells were edited with TALENs to seek out and kill only the leukemia cells in Layla’s body. Only a few months after the treatment Layla had no traces of leukemia in her body. While this treatment used an older, more expensive gene editing technique known as TALENs the advent of the cheaper and easier CRISPR/Cas9 technology may make more treatments like this a reality.
