Genetic testing poses fundamental questions for insurance. Testing can predict a low probability of future illness and disability, which can help promote the insurability of individuals with a family history of genetic risk, but it can also invite insurers to reject applicants, increase premiums, exclude people with certain illnesses and disabilities, and otherwise adjust the underwriting processes for individuals with certain genotypes. In the workplace, these issues may cause employers who offer or pay for insurance to alter their hiring behavior, (...) either by selecting those with desirable genetic makeup or rejecting, dismissing, or reassigning those who carry an unwanted risk, ultimately threatening employability and the safety net that insurance is intended to provide.
