Hákon Hákonarson and deCODE genetics CEO Kári Stefánsson used to consider each other friends. Hákonarson, the former vice president of business development at the Icelandic biopharmaceutical company, used to ride horses with Stefánsson and spend time with him outside of work. That all ended in May, 2006, when Hákonarson left deCODE to direct and help form the new Center for Applied Genomics at the Children's Hospital of Philadelphia (CHOP).
