Final answer:
GINA prevents employers and health insurers from discriminating against individuals based on genetic information, safeguarding against the potential misuse of genetic data in employment and health coverage decisions.
Step-by-step explanation:
Under the Genetic Information Nondiscrimination Act (GINA), employers are prohibited from discriminating against employees because of genetic information. This includes any use of genetic information in decisions about hiring, firing, job assignments, promotions, and other terms of employment. GINA also bars health insurers from denying coverage or increasing costs of premiums based on one's genetic makeup. While private insurers must comply with these regulations, the act does not cover life, long-term care, or disability insurance. It's noteworthy that these protections were a response to concerns that arose during the Human Genome Project about the potential misuse of genetic data. The enforcement of GINA, alongside other anti-discrimination laws such as the Civil Rights Act and the Americans with Disabilities Act (ADA), is aimed at ensuring ethical treatment of individuals in the workplace and in health insurance coverage.
