Perspectives in genetic screening. Principles and implications

Recent advances in genetic identification and characterization of a number or hereditary disorders have led to increased possibilities for genetic testing and screening. The context and methods of screening are important given that identification of otherwise healthy persons as being presymptomatic or at increased risk for genetic diseases may have serious consequences for their future lifestyle, employment, and insurability. This article examines general principles for genetic screening, including goals, delivery issues, and professional and lay responses to screening and counseling, and recommends areas in which social psychological research on screening is needed.
