I was lucky enough to see a presentation at a pharmaceutical company. Essentially, it was a pitch for us asking them for information. The idea is that a bunch of their customers have answered a ton of questions, in addition to the gene-chip data they have. Then, they can also opt-in (it was a pretty high percentage that do) to answer additional questions as part of further study. This would be a very valuable recruiting tool for clinical trials, as it could greatly reduce the lead time on recruitment by just offering customers within a certain distance of participating centers who are known to have or be susceptible to a disease or condition. It's not that the gene data is considered perfect, but that they also have a huge database of additional questionnaire type data that can be leveraged.
