Plunging into the gene pool: even though the legal landscape has changed, concerns about the abuse of genetic testing persist.

• Author: Johnson, Alissa

Is your genetic information safe? Sixteen years have passed since Wisconsin Governor Tommy Thompson signed the first state law to prevent genetic discrimination in March 1991. A tidal wave of genetics legislation followed, propelled by the anticipated completion of the Human Genome Project to sequence and map the genes that make up a human being. Public fears continue, however, over the possible abuse of genetic testing technology.

Although genetic support groups and counselors often hear about cases of discrimination, few complaints have ever been filed. Almost all states restrict the use of genetic information in health insurance, and over half prohibit genetic discrimination in employment. The complexity of genetic discrimination laws and the difficulty of determining how they apply (depending, for example, on the type of genetic testing conducted, the genetic information acquired, the health status of the employee or insured, and how the information was used) may deter people who believe they were harmed from taking action. Furthermore, a given set of circumstances play out differently from state to state because the language of the laws varies. Without putting these laws to the test, it is too early to tell which states have followed a successful course.

DISCRIMINATION DOES HAPPEN

That's not to say that no one has faced and fought genetic discrimination. The story of Heidi Williams, who has alpha-1 antitripsyn (Alpha-1) deficiency, is an example of the abuse many Americans fear.

Because of a deficiency of the alpha-1 antitrypsin protein, people with Alpha-1 are susceptible to hepatitis, cirrhosis, emphysema and chronic obstructive pulmonary disease. When Williams applied for health insurance on behalf of her two healthy children, who are carriers of only one copy of the gene for Alpha-1, coverage was denied based on their genetic makeup. As carriers, the Williams children are at little or no risk of developing the disease. Carriers may pass on the disease only if they have a child with another carrier. It is generally accepted that everyone carries three to eight recessive genes for serious genetic disorders, meaning everyone is potentially susceptible to the discrimination Williams experienced.

Through appeals and with the help of Alpha-1 experts, Williams provided information to the insurance company about what it means to be a carrier for Alpha-1. After repeated denials, the decision was finally reversed but only after the media reported the story.

"No one should have to force an insurance company to cover perfectly healthy children," Williams said in testimony to the Secretary's Advisory Committee on Genetics, Health and Society. "I should not have had to spend the better part of six months wondering if the decision to have my children's genetic status verified by their pediatrician was a huge mistake."

Williams says she is not alone. "Today, there is a current of fear...
