I wrote this article after Harvard’s George Church and several others published a proposal to make a synthetic human genome. They are calling their project HGP-Write. Prior to this proposal I had been researching some of the flaws in genetic testing for a fiction piece. I came across a fascinating article in The Atlantic on forensics and false positives in DNA matching. I also read a research paper on “genetic superheroes” that calls into question some of our assumptions about fully penetrant diseases.
