genie-out-of-the-bottle writes "California's Department of Public Health sent cease-and-desist notices to 13 companies that market genetic testing directly to consumers. Slashdot covered launch of these services here and here. Allegedly, under state law, California residents must submit a doctor's order to have a genetic test run. It will be interesting to see if the government will actually succeed in putting the genetic genie back in the bottle provided all you need for testing is a few drops of saliva. Given the availability of the technology this closely resembles US government efforts to block export of strong encryption product back in 90s. How far they are willing to push it this time is yet to be seen."
