Overview

23andMe pioneered direct-to-consumer genetic testing, combining ancestry analysis with FDA-approved health reports. However, our analysis reveals severe privacy concerns: the company's business model is built on monetizing genetic data through pharmaceutical partnerships, research consent is pre-checked by default, and recent financial troubles have raised serious questions about long-term data security. The 2023 data breach affecting 6.9 million users compounds these concerns.

Key Concerns

  • Pharmaceutical Partnerships: Major revenue stream from selling access to genetic data to pharmaceutical companies including GSK partnership worth $300M+.
  • Pre-Checked Research Consent: Research participation is opt-out, not opt-in; many users unknowingly consent during registration.
  • 2023 Data Breach: Massive breach exposed 6.9 million users' ancestry data and DNA relative information.
  • Financial Instability: Company facing severe financial difficulties, raising concerns about potential sale of data assets.
  • Partial Deletion Only: Cannot fully delete genetic data; some information retained in research databases.
  • Relative Exposure: DNA Relatives feature exposes family members who never consented to testing.
  • Health Data Sensitivity: Health reports reveal genetic predispositions that could affect insurance and employment.
  • Law Enforcement Requests: Has received and complied with law enforcement requests for genetic data.

Positive Aspects

  • FDA-Approved Health Reports: Only service with FDA authorization for certain health predisposition reports.
  • Research Transparency: Published list of research studies using customer data.
  • Sample Destruction Option: Users can request physical sample destruction after processing.

Data Collection Summary

23andMe collects saliva samples containing DNA, extracts genetic information covering approximately 600,000 genetic markers, and stores both raw data and derived health/ancestry reports. Data feeds into research databases used by pharmaceutical partners. The company also collects extensive self-reported health surveys that are combined with genetic data. Recent financial troubles and board departures have raised concerns about the security and potential sale of this massive genetic database containing millions of profiles.
