WASHINGTON — Distrust for science experiments and involvement in genetic research is deeply rooted for some cultures living in the United States.

The story of Henrietta Lacks and the Tuskegee Syphilis Experiment are some of the first things that come to mind for some black Americans when the topic of DNA testing is presented.

Lacks was an underprivileged tobacco farmer who had her cells taken without consent in the 1950s. They were the first immortal human cells that could be grown in a test tube.

Lacks’ cells were crucial in many medical breakthroughs, such as the polio vaccine, in vitro fertilization, cloning, gene mapping and more.

Her family lived in poverty after her death, but her cells were being sold and bought throughout the medical community.

Within the same time period, in Alabama, hundreds of African Americans were unethically infected with syphilis during a study by the U.S. government that ended in 1972.

According to the Centers for Disease Control for Prevention, the men were not given the facts needed to offer informed consent and were never given acceptable treatment for the disease.

"We don't store or share any genetic information," said. Gina Paige, co-founder of African Ancestry, said. "That’s a particular concern for our community due to the history and the legacy of how our genetic material has been handled in the past."

With the increasing popularity in DNA genetic testing, WUSA9 looked at privacy policies and security procedures for three companies: African Ancestry, Ancestry DNA and 23andMe.

The purpose is to provide consumers with the information needed to make informed decisions before or after purchasing a genetic DNA test.

How do DNA testing companies store your DNA samples?

For all three of the DNA testing companies, customers are required to submit a saliva sample, but the way your genetic material is used depends on what is outlined in privacy statements.

African Ancestry:

  • Each DNA sample becomes the property of the company as soon as it is delivered.
  • The company keeps the DNA samples and analysis confidential to the extent permitted by law.
  • After the company delivers its results, it will destroy the sample.

Ancestry DNA:

  • Once a laboratory partner has given DNA results, the DNA and saliva are stored for future testing.
  • Future testing may be done if the customer agrees to research. Read the AncestryDNA Informed Consent here
  • Customers can request that their DNA samples be destroyed by contacting AncestryDNA’s member services department.
  • If customers previously agreed to research, Ancestry DNA’s website claims it will not be able to remove genetic information from active or completed research projects. However, the company will not use genetic information after a requested deletion for any new research projects.

23andMe:

  • Customer's saliva samples are shipped to a third-party laboratory.
  • The company’s biobanking consent document explains customers agree to have 23andme and its contractors access and analyze stored samples of saliva or DNA extracted from saliva. Read the company document here
  • Unless customers agree to the company storing their DNA or saliva, it will be destroyed after the laboratory finishes testing -- Subject to the laboratory's legal and regulatory requirements.
  • Customers can update preferences to destroy stored samples in the "Account Settings" section on the website.
