On May 1, 2008, the US House of Representatives approved the Genetic Information Nondiscrimination Act by an over whelming 414-1 margin, just eight days after the Senate also voted unanimously in favor of the bill. When the bill becomes law, which may occur before the end of May 2008, employers and health insurance companies will be expressly prohibited from discriminating against or refusing coverage to individuals based on results of genetic testing.
