In a landmark medical breakthrough, a baby boy with DNA from three different people has been born in the UK. The child was conceived using a technique called “spindle nuclear transfer,” which involves replacing the nucleus of a donor egg with that of the mother, and then fertilizing it with sperm from the father. The procedure is intended to prevent certain genetic disorders from being passed on from the mother to the child. The baby’s mother carries a rare genetic mutation that causes a mitochondrial disease, which can lead to serious health problems. This technique allows for the baby to be born with healthy mitochondria from the donor egg. While this is a significant scientific advancement, it also raises ethical concerns about the implications of altering the genetic makeup of a human being.
