Who Has Your Genetic Data?

DNA testing companies likely retain your genetic information. It commonly happens when you’ve used their services and didn’t explicitly request to delete your data afterward. Even if you no longer access the website or keep tabs on the company, they can keep your DNA files.

You should read a company’s policies to determine who can access your DNA and address your privacy concerns. Some companies will continue storing your sample without your request for deletion, making it potentially accessible.

DNA testing companies can sell your genetic data or even share it with law enforcement and third parties, like medical researchers and pharmaceutical companies.

DNA testing companies working with Clinical Laboratory Improvement Amendments (CLIA) certified labs must keep records of your DNA, sex, and birth date for quality control.

Why Delete Your DNA Data?

You should delete your DNA data for your own personal safety, privacy, and security. Even if a DNA testing company has great security, the wrong people can still use or access the most secure servers and anything can happen to your data.

DNA testing services have security measures and privacy policies to protect their customers. They know how sensitive your data is.

However, despite the precautionary measures to ensure data safety, the steps that DNA companies take may only be partially foolproof. 

As long as your raw data file remains on your DNA testing company’s database, hackers, law enforcers, insurance companies, and other third parties can access your information.

Below are some examples where genetic information was compromised:

  • MyHeritage had a data breach that exposed the emails and passwords of 92 million users. The hackers didn’t directly access DNA data, but they could find people’s information.
  • Law enforcement used DNA information stored by GEDMatch to track down the Golden State Killer.2
  • FamilyTree DNA gave the FBI access to its database without a subpoena.3
  • The U.S. Congress approved a bill that allows companies to get DNA testing for their employees. Employees must also share this information with their employers.4

If you’re concerned about the security and privacy of your raw DNA, you should ask for your sample to be destroyed and your data to be permanently deleted.

Some companies have the option to download your raw DNA before deleting your information from their database.

Key Takeaways on DNA Data Deletion

  • AncestryDNA and 23andMe top the list of the most private genetic tests. They have comprehensive privacy policies and allow users to delete their DNA data. 
  • Not all genetic testing companies have a straightforward or transparent process for data deletion. You may consider this factor in choosing a DNA testing company.
  • Other companies let you download your raw DNA. You can upload this data to other sites and learn more about your DNA.
  • DNA testing companies can, with your consent, sell your genetic data to third parties or share them with law enforcement.
  • Your genetic data can potentially be misused. But it shouldn’t stop you from sharing your genetic data with a reliable company. Always check a company’s security and data handling policies when opting for its services.
