Answer:

In the United States there are existing state laws to protect people from genetic discrimination in areas such as insurance companies and workplaces.

In many cases, both workplaces and insurance companies require genetic testing before granting a job or an insurance policy.

A federal law - Genetic Information Nondiscrimination Act or GINA - protects people against this requirement of their future employers or any insurance company and guarantees, with certain exceptions, the possibility of obtaining a job or medical insurance.
