Predictive genetic testing has exploded in the medical realm, offering doctors better tools to identify disease risk before symptoms emerge. But the legal framework protecting people from genetic discrimination lags far behind the science. Researchers and legal experts worry that outdated federal guidelines could leave workers vulnerable to employment discrimination based on DNA information.
The Genetic Information Nondiscrimination Act (GINA) of 2008 explicitly prohibits health insurers and employers from requesting genetic tests or using genetic information in hiring decisions. Yet GINA has significant gaps. The law does not cover life insurance, disability insurance, or long-term care insurance, meaning insurers in those sectors can legally access genetic data and adjust premiums accordingly.
Legal scholars point out that the act's language predates modern polygenic risk scores, which use thousands of genetic variants to predict disease susceptibility across complex conditions like heart disease, diabetes, and certain cancers. These scores represent a fundamentally different type of genetic information than the single-gene disorders GINA contemplated.
The real challenge emerges as genetic testing becomes routine in clinical practice. If your doctor orders a polygenic risk score and that information enters your medical record, it theoretically falls under GINA protection at work. However, legal experts warn that the law's enforcement mechanisms remain weak. The Equal Employment Opportunity Commission has brought few cases under GINA since its passage.
Employers increasingly use health data in other ways too. Workplace wellness programs often incentivize genetic testing, and data brokers are rapidly accumulating genetic information from direct-to-consumer DNA tests. These pathways could expose genetic data without triggering GINA protections.
Advocates argue that federal law needs updating to address polygenic risk scores explicitly and extend protections to life and disability insurance. Some states have begun filling gaps, but the patchwork approach creates uncertainty for individuals navigating genetic testing decisions.
