The FDA authorization of direct-to-consumer genetic testing for three pathogenic variants: a twitter analysis of the public's response.

Objectives: In March 2018, the Food and Drug Administration (FDA) announced its authorization of a direct-to-consumer (DTC) genetic test for three pathogenic variants. We sought to determine to whether social media discussion increased following the authorization, who was driving social media conversations, and what topics were discussed.

Methods: Using Crimson Hexagon, we described tweets before, during, and after the FDA announcement authorizing 23andMe to return results (3/4/18-3/10/18).
