"Tests Purchased from Four Web Sites Mislead Consumers": 2006 US GAO Report on 'Nutrigenetic' Testing: What the GAO found: "The results from all the tests GAO purchased mislead consumers by making predictions that are medically unproven and so ambiguous that they do not provide meaningful information to consumers."
Note that these conclusions apply to Nutrigenetic testing only, and not to the other kinds of direct to consumer genetic testing services (deCODEme, 23andMe, etc.).
