Dads all have their talents. Mine was a whiz at fixing mechanical toys, such as my orange, flower-printed, wind-up owl. Bea Reinhoff's dad trained as a geneticist in the 1980s, although he ultimately chose to leave medicine in order to fund biotech startups. But when Bea was born with some unusual symptoms and no clear diagnosis, Hugh Reinhoff returned to genetics again. He bought $2,000 worth of equipment and sequenced Bea's genome at home, Nature reported in 2007. At the time, nobody had ever used genome sequencing to pinpoint the cause of a disease in a single person.
