GINA stands for the Genetic Information Nondiscrimination Act, a federal law signed in 2008 that prevents health insurers and employers from using your genetic information against you. If you’ve had a genetic test, or if a close family member has been diagnosed with a hereditary condition, GINA is the law that keeps that information from affecting your health coverage or your job.
What GINA Actually Protects
GINA is built on a straightforward principle: it’s unfair to penalize someone for a health condition they might never develop. The law has two main parts. Title I covers health insurance, and Title II covers employment. Together, they create a firewall between your genetic data and the decisions that insurers and employers make about you.
The law defines “genetic information” broadly. It includes the results of your own genetic tests, the results of a family member’s genetic tests, family medical history, and even the fact that you or a relative sought genetic counseling or testing. If you’re undergoing fertility treatment, the genetic information of an embryo or fetus is also covered.
Health Insurance Protections
Title I of GINA prohibits health insurers from using genetic information in any underwriting decision. That includes setting your premiums, determining your eligibility, applying pre-existing condition exclusions, and deciding whether to create, renew, or replace your coverage. A health plan cannot ask you to take a genetic test as a condition of enrollment, and it cannot use a family member’s diagnosis of a hereditary disease as a reason to charge you more.
These rules apply to group health plans, individual market insurers, and Medicare supplemental (Medigap) policies. GINA works alongside HIPAA’s privacy protections: genetic information is classified as protected health information, and health plans are explicitly banned from using or disclosing it for underwriting purposes.
Employment Protections
Title II makes it illegal for employers to use genetic information in any employment decision. That covers hiring, firing, pay, promotions, layoffs, job assignments, training, and benefits. The Equal Employment Opportunity Commission (EEOC) enforces this part of the law, and it applies to private employers with 15 or more employees, as well as employment agencies, labor unions, and apprenticeship programs.
Employers aren’t just barred from acting on genetic information. They’re also restricted from requesting, requiring, or purchasing it in the first place. If an employer does come across your genetic information inadvertently (through a wellness program questionnaire, for example), that information must be kept confidential and stored separately from your regular personnel file. The EEOC’s position is clear: genetic information is never relevant to an individual’s current ability to work.
The Manifest Disease Distinction
This is where GINA’s limits become important to understand. The law only protects you before a genetic condition shows symptoms. Once a disease has “manifested,” meaning a qualified healthcare professional has diagnosed it or could reasonably diagnose it based on signs and symptoms, GINA no longer applies to that specific condition. At that point, other laws like the Americans with Disabilities Act or the Affordable Care Act may offer protection instead.
There’s a key nuance here: a diagnosis counts as manifest only if it’s based on clinical symptoms, not on genetic test results alone. If a doctor can only identify your condition through a DNA test and you have no symptoms, GINA still protects you. The law draws a line between the probability of getting sick and actually being sick.
For example, if you carry a gene variant linked to a higher risk of breast cancer but have no symptoms, GINA protects that information from being used by your insurer or employer. If you’re later diagnosed with breast cancer, GINA no longer covers that diagnosis, though it still protects the underlying genetic test result from being used to discriminate in unrelated ways.
What GINA Does Not Cover
GINA has several notable gaps. The law does not apply to life insurance, disability insurance, or long-term care insurance. An insurer in any of those markets can legally ask about genetic test results or family history and factor that information into coverage decisions. Some states have passed their own laws to fill this gap, but federal protection stops at health insurance and employment.
GINA also does not apply to employers with fewer than 15 employees. Members of the military covered under TRICARE fall outside GINA’s employment protections as well, though they may have separate protections under military-specific regulations.
And as noted above, GINA does not prevent insurers or employers from making decisions based on a condition you already have. It is designed to protect people from being treated unfairly based on what their DNA suggests could happen, not what has already happened.
Why GINA Matters Now
Genetic testing has become far more common since GINA was enacted. Consumer DNA kits, expanded carrier screening during pregnancy, and tumor profiling in cancer care all generate the kind of data GINA was designed to protect. Without the law, a person might reasonably avoid testing that could guide their medical care out of fear that the results would raise their premiums or cost them a promotion.
If you believe an employer or health insurer has used your genetic information improperly, Title II complaints go to the EEOC, which handles them through the same process used for other workplace discrimination claims. Title I complaints involving health insurers are handled by the Department of Health and Human Services and, for employer-sponsored plans, the Department of Labor. Filing is free and can typically be initiated online or by contacting the relevant agency directly.
