Genetic Testing

The FDA has given approval to 23andMe for its genetic tests under a 510K ruling. They state:

The U.S. Food and Drug Administration today authorized for marketing 23andMe’s Bloom Syndrome carrier test, a direct-to-consumer (DTC) genetic test to determine whether a healthy person has a variant in a gene that could lead to their offspring inheriting the serious disorder. Along with this authorization, the FDA is also classifying carrier screening tests as class II. In addition, the FDA intends to exempt these devices from FDA premarket review. The agency plans to issue a notice that announces the intent to exempt these tests and that provides a 30-day period for public comment. This action creates the least burdensome regulatory path for autosomal recessive carrier screening tests with similar uses to enter the market.

In addition they also specifically stated:

“The FDA believes that in many circumstances it is not necessary for consumers to go through a licensed practitioner to have direct access to their personal genetic information. Today’s authorization and accompanying classification, along with FDA’s intent to exempt these devices from FDA premarket review, supports innovation and will ultimately benefit consumers,” said Alberto Gutierrez, Ph.D., director of the Office of In Vitro Diagnostics and Radiological Health in the FDA’s Center for Devices and Radiological Health. “These tests have the potential to provide people with information about possible mutations in their genes that could be passed on to their children.”

The problem is that consumers would generally have no clue as how to interpret the results and even more so most physicians would be equally at a loss.

Certain genetic markers are definitive and others are suggestive. How is a consumer to understand that? This may present a substantial challenge to the health care system.
