Genetic Privacy: What It Is and How to Protect It

Genetic privacy refers to an individual’s right to control the access and use of their unique genetic information. In the rapidly evolving digital landscape, where genetic data is becoming more accessible, understanding and protecting this information has become increasingly significant. This protection extends to ensuring that personal genetic details are not misused or shared without explicit consent, reflecting a growing concern for individual autonomy over biological data.

What Genetic Privacy Means

Genetic information encompasses DNA sequences, genetic test results, and family health histories. This data is uniquely sensitive because it is largely immutable, meaning it does not change over a person’s lifetime. It also holds predictive power regarding future health conditions or predispositions. Furthermore, this information is inherently shared with biological relatives, meaning a decision made by one family member about their genetic data can have implications for others.

Where Your Genetic Data Comes From

Genetic data can be collected through several pathways. Direct-to-consumer (DTC) genetic testing companies, such as 23andMe or AncestryDNA, are a prominent source, where individuals provide saliva samples for insights into their ancestry or health predispositions. Healthcare providers also collect genetic information through medical records, diagnostic tests for specific conditions, and family health histories. Additionally, participation in scientific research studies often involves collecting genetic data to advance understanding of various diseases or human traits. Forensic databases, maintained by law enforcement agencies, can also contain genetic profiles derived from crime scene evidence or convicted offenders.

Potential Harms of Data Misuse

Unauthorized access or misuse of genetic information presents significant risks. A primary concern is genetic discrimination, where genetic predispositions might be used to deny employment or insurance coverage. For example, an employer could use genetic information to make hiring or firing decisions, or a health insurer might deny coverage or adjust premiums based on an individual’s genetic profile.

Data breaches represent another threat, where sensitive genetic information could be exposed to unauthorized parties. Even data that has been “anonymized” can sometimes be re-identified, potentially linking individuals back to their genetic profiles. Genetic data may also be shared with third parties, such as pharmaceutical companies for drug development or law enforcement agencies for investigations, often without explicit consent from the individual.

Legal Safeguards and Limitations

In the United States, the Genetic Information Nondiscrimination Act (GINA) of 2008 offers some protection against genetic discrimination. GINA specifically prohibits health insurers from using genetic information to determine eligibility or set premiums, and it prevents employers from using genetic information in employment decisions such as hiring, firing, or promotions.

However, GINA has notable limitations; it does not extend its protections to life, disability, or long-term care insurance. Moreover, GINA does not apply to employers with fewer than 15 employees, nor does it cover individuals receiving insurance through the federal government or the military.

While the Health Insurance Portability and Accountability Act (HIPAA) provides general privacy protections for health information, it does not directly regulate direct-to-consumer genetic testing companies. This regulatory gap means that DTC companies are not always bound by the same strict privacy requirements as healthcare providers, leaving consumers with fewer federal protections regarding how their data is shared or used.

Protecting Your Own Genetic Information

Individuals can take steps to safeguard their genetic privacy. Before using direct-to-consumer genetic testing services, thoroughly read and understand the company’s terms and conditions, paying close attention to their data sharing policies. Many companies provide information in their “privacy policy” or “privacy center” regarding how data will be used for secondary purposes like research or advertising. Consumers should look for options to opt out of data sharing for research or with third parties.

Exercising caution when participating in research studies is also advisable, ensuring that clear privacy protocols are in place and understood. It is also important to be aware that even if a company promises not to share data, they may be legally compelled to disclose information to authorities in response to a warrant or court order.
