Genetic identification of susceptibility to common diseases : a new era of preventive medicine? Baird, Patricia A.
The benefits, harms and limitations of screening for genetic susceptibility in order to prevent common diseases are discussed. Reasons that premature or unwise application of genetic identification may occur are enumerated. It is concluded that the identification of susceptible "risk" genotypes by screening is unlikely to be an effective or equitable strategy for the prevention of common complex diseases of environmental-gene interaction. The need for public policy, and the criteria to be met before screening should be permitted, are outlined.
