Direct-to-consumer genomewide profiling to assess disease risk provides information about a person's genetic risk of 20 to 40 common polygenic diseases. The tests simultaneously genotype approximately 500,000 variant bases of a person's DNA. Consumers can purchase these tests, currently priced between $400 and $2,000, on the Internet <\/div>
<\/div>
Proponents argue that providing this type of information directly to consumers may result in improved compliance with health-screening practices and more healthful lifestyle choices. <\/div>
<\/div>
Skeptics assert that such testing has the potential to cause harm, including anxiety and increased use of unnecessary and expensive screening and medical procedures. <\/div>
<\/div>
The clinical validity and utility of these tests have not been demonstrated, and given their cost, many observers argue that their sale raises consumer-protection issues.
<\/div>
In a recent study published in the NEJM, subjects who chose to undergo direct-to-consumer genomewide testing, had no short-term changes in psychological health, diet and exercise behavior, or use of screening tests.<\/div>
