World's First Baby Born With DNA From Three ParentsIn a world first, a baby has been born with DNA from three biological parents. The 5-month-old boy, born to Jordanian parents, was conceived with the help of a U.S. team based in Mexico using a controversial technique that allows parents with rare genetic mutations to have healthy babies, the New Scientist reports. The mother

carries genes for Leigh syndrome, a rare genetic disorder characterized by the degeneration of the central nervous system; the brain, sp

inal cord, and optic nerve. Although she is healthy, her first two children died because of Leigh syndrome, so she sought out the help of t

he New Hope Fertility Center in New York. Related Stories
