When Chinese researcher He Jiankui stunned the scientific community in November 2018 with the announcement that he had created the first genetically edited babies, he performed a medically unnecessary procedure well before scientists considered the consequences of altering the human genome. This story is discussed in the new two-part documentary The Gene: An Intimate History, produced by Ken Burns and based on the best-selling book by Dr. Siddhartha Mukherjee. The show focuses on three main aspects: the historical biography of the human genome, doctors currently at the forefront of genetic treatments, and present-day personal stories of patients whose lives could be transformed by new scientific breakthroughs. Alongside treatments, experts will also speak on the complex ethical questions they raise. But you don’t have to wait until April to preview this documentary: The Gene is coming to GPB for a special sneak peek screening on March 10 before its TV air dates on April 7 and 14, 2020.
