This book explores implicit choices made by researchers, policy makers, and funders regarding who benefits from society's investment in health research. The authors focus specifically on genetic research and examine whether such research tends to reduce or exacerbate existing healthdisparities. Using case examples to illustrate the issues, the authors trace the path of genetics research from discovery, through development and delivery, to health outcomes. Topics include breast cancer screening and treatment, autism research, pharmacogenetics, prenatal testing, newborn screening, and youthsuicide prevention. Each chapter emphasizes the societal context of genetic research and illustrates how science might change if attention were paid to the needs of marginalized populations. Written by experts in genetics, health, and philosophy, this book argues that the scientific enterprise has aresponsibility to respond to community needs to assure that research innovations achieve much needed health impacts.
