How tiny variations in our personal DNA can determine how we look, how we behave, how we get sick, and how we get well. News stories report almost daily on the remarkable progress scientists are making in unraveling the genetic basis of disease and behavior. Meanwhile, new technologies are rapidly reducing the cost of reading someone's personal DNA (all six billion letters of it). Within the next ten years, hospitals may present parents with their newborn's complete DNA code along with her footprints and APGAR score. In Genetic Twists of Fate, distinguished geneticists Stanley Fields and Mark Johnston help us make sense of the genetic revolution that is upon us. Fields and Johnston tell real life stories that hinge on the inheritance of one tiny change rather than another in an individual's DNA: a mother wrongly accused of poisoning her young son when the true killer was a genetic disorder; the screen siren who could no longer remember her lines because of Alzheimer's disease; and the president who was treated with rat poison to prevent another heart attack. In an engaging and accessible style, Fields and Johnston explain what our personal DNA code is, how a few differences in its long list of DNA letters makes each of us unique, and how that code influences our appearance, our behavior, and our risk for such common diseases as diabetes or cancer.

Heritable human genome editing - making changes to the genetic material of eggs, sperm, or any cells that lead to their development, including the cells of early embryos, and establishing a pregnancy - raises not only scientific and medical considerations but also a host of ethical, moral, and societal issues. Human embryos whose genomes have been edited should not be used to create a pregnancy until it is established that precise genomic changes can be made reliably and without introducing undesired changes - criteria that have not yet been met, says Heritable Human Genome Editing. From an international commission of the U.S. National Academy of Medicine, U.S. National Academy of Sciences, and the U.K.'s Royal Society, the report considers potential benefits, harms, and uncertainties associated with genome editing technologies and defines a translational pathway from rigorous preclinical research to initial clinical uses, should a country decide to permit such uses. The report specifies stringent preclinical and clinical requirements for establishing safety and efficacy, and for undertaking long-term monitoring of outcomes. Extensive national and international dialogue is needed before any country decides whether to permit clinical use of this technology, according to the report, which identifies essential elements of national and international scientific governance and oversight.

"A lucid, thought-provoking account of the case for 'nature' as a determinant of personality."—Peter D. Kramer, Author of Listening to Prozac and Should You Leave? Nowhere is the nature-nurture controversy being more arduously tested than in the labs of world-renowned molecular scientist Dean Hamer, whose cutting-edge research has indisputably linked specific genes to behavioral traits, such as anxiety, thrill-seeking, and homosexuality. The culmination of that research is this provocative book, Living with Our Genes. In it, Dr. Hamer reveals that much of our behavior—how much we eat and weigh, whether we drink or use drugs, how often we have sex—is heavily influenced by genes. His findings help explain why one brother becomes a Wall Street trader, while his sibling remains content as a librarian, or why some people like to bungee-jump, while others prefer Scrabble. Dr. Hamer also sheds light on some of the most compelling and vexing aspects of personality, such as shyness, aggression, depression, and intelligence. In the tradition of the bestselling book Listening to Prozac, Living with Our Genes is the first comprehensive investigation of the crucial link between our DNA and our behavior. "Compulsive reading, reminiscent of Jared Diamond, from a scientist who knows his stuff and communicates it well."—Kirkus Reviews "A pioneer in the field of molecular psychology, Hamer is exploring the role genes play in governing the very core of our individuality. Accessible . . . provocative."—Time "Absolutely terrific! I couldn't put it down."—Professor Robert Plomin, Social, Genetic & Developmental Psychiatry Research Center, Institute of Psychiatry

Raising hopes for disease treatment and prevention, but also the specter of discrimination and "designer genes," genetic testing is potentially one of the most socially explosive developments of our time. This book presents a current assessment of this rapidly evolving field, offering principles for actions and research and recommendations on key issues in genetic testing and screening. Advantages of early genetic knowledge are balanced with issues associated with such knowledge: availability of treatment, privacy and discrimination, personal decision-making, public health objectives, cost, and more. Among the important issues covered: Quality control in genetic testing. Appropriate roles for public agencies, private health practitioners, and laboratories. Value-neutral education and counseling for persons considering testing. Use of test results in insurance, employment, and other settings.

Program discusses the Human Genome Project, the science behind it, and the ethical, legal and social issues raised by the project.

In light of scientific advances such as genomics, predictive diagnostics, genetically engineered agriculture, nuclear transfer cloning, and the manipulation of stem cells, the idea that genes carry predetermined molecular programs or blueprints is pervasive. Yet new scientific discoveries—such as rna transcripts of single genes that can lead to the production of different compounds from the same pieces of dna—challenge the concept of the gene alone as the dominant factor in biological development. Increasingly aware of the tension between certain empirical results and interpretations of those results based on the orthodox view of genetic determinism, a growing number of scientists urge a rethinking of what a gene is and how it works. In this collection, a group of internationally renowned scientists present some prominent alternative approaches to understanding the role of dna in the construction and function of biological organisms. Contributors discuss alternatives to the programmatic view of dna, including the developmental systems approach, methodical culturalism, the molecular process concept of the gene, the hermeneutic theory of description, and process structuralist biology. None of the approaches cast doubt on the notion that dna is tremendously important to biological life on earth; rather, contributors examine different ideas of how dna should be represented, evaluated, and explained. Just as ideas about genetic codes have reached far beyond the realm of science, the reconceptualizations of genetic theory in this volume have broad implications for ethics, philosophy, and the social sciences.

In the fifty years since DNA was discovered, we have seen extraordinary advances. For example, genetic testing has rapidly improved the diagnosis and treatment of diseases such as Huntington's, cystic fibrosis, breast cancer, and Alzheimer's. But with this new knowledge comes difficult decisions for countless people, who wrestle with fear about whether to get tested, and if so, what to do with the results. Am I My Genes? shows how real individuals have confronted these issues in their daily lives. Robert L. Klitzman interviewed 64 people who faced Huntington's Disease, breast and ovarian cancer, or Alpha-1 antitrypsin deficiency. The book describes--often in the person's own words--how each has wrestled with the vast implications that genetics has for their lives and their families. Klitzman shows how these men and women struggle to make sense of their predicament and its causes. They confront a series of quandaries--whether to be tested; whether to disclose their genetic risks to parents, siblings, spouses, offspring, friends, doctors, insurers, employers, and schools; how to view and understand themselves and their genetics; what treatments, if any, to pursue; whether to have children, adopt, screen embryos, or abort; and whether to participate in genetic communities. In the face of these uncertainties, they have tried to understand these tests and probabilities, avoid fatalism, anxiety, despair, and discrimination, and find hope, meaning, and a sense of wholeness. Forced to wander through a wilderness of shifting sands, they chart paths that many others may eventually follow. Klitzman captures here the voices of pioneers, some of the first to encounter the personal dilemmas introduced by modern genetics. Am I My Genes? is an invaluable account of their experience, one that will become all the more common in the coming years. "An extraordinary exploration...probing the many roles and implications of genetics in our lives today.... Filled with astonishing insights, this riveting book is vital reading for us all." --Paula Zahn "Klitzman lucidly discusses the moral and psychological complexities that come in the wake of genetic testing.... An important book for anyone who has the genes for pathology, which is all of us, and I recommend it highly." --Kay Redfield Jamison, author of An Unquiet Mind "An illuminating voyage through the medical, familial and existential quandaries faced by those of us at genetic risk." --Thomas H. Murray, President and CEO, The Hastings Center

In a book that promises to change the way we think and talk about genes and genetic determinism, Evelyn Fox Keller, one of our most gifted historians and philosophers of science, provides a powerful, profound analysis of the achievements of genetics and molecular biology in the twentieth century, the century of the gene. Not just a chronicle of biology’s progress from gene to genome in one hundred years, The Century of the Gene also calls our attention to the surprising ways these advances challenge the familiar picture of the gene most of us still entertain. Keller shows us that the very successes that have stirred our imagination have also radically undermined the primacy of the gene—word and object—as the core explanatory concept of heredity and development. She argues that we need a new vocabulary that includes concepts such as robustness, fidelity, and evolvability. But more than a new vocabulary, a new awareness is absolutely crucial: that understanding the components of a system (be they individual genes, proteins, or even molecules) may tell us little about the interactions among these components. With the Human Genome Project nearing its first and most publicized goal, biologists are coming to realize that they have reached not the end of biology but the beginning of a new era. Indeed, Keller predicts that in the new century we will witness another Cambrian era, this time in new forms of biological thought rather than in new forms of biological life.

As the population of older Americans grows, it is becoming more racially and ethnically diverse. Differences in health by racial and ethnic status could be increasingly consequential for health policy and programs. Such differences are not simply a matter of education or ability to pay for health care. For instance, Asian Americans and Hispanics appear to be in better health, on a number of indicators, than White Americans, despite, on average, lower socioeconomic status. The reasons are complex, including possible roles for such factors as selective migration, risk behaviors, exposure to various stressors, patient attitudes, and geographic variation in health care. This volume, produced by a multidisciplinary panel, considers such possible explanations for racial and ethnic health differentials within an integrated framework. It provides a concise summary of available research and lays out a research agenda to address the many uncertainties in current knowledge. It recommends, for instance, looking at health differentials across the life course and deciphering the links between factors presumably producing differentials and biopsychosocial mechanisms that lead to impaired health.
