Life Histories Of Genetic Disease

A richly detailed history that “uncovers the challenges and limitations of our increasing reliance on genetic data in medical decision making” (Shobita Parthasarathy, author of Building Genetic Medicine). Medical geneticists began mapping the chromosomal infrastructure piece by piece in the 1970s by focusing on what was known about individual genetic disorders. Five decades later, their infrastructure had become an edifice for prevention, allowing expectant parents to test prenatally for hundreds of disease-specific mutations using powerful genetic testing platforms. In this book, Andrew J. Hogan explores how various diseases were “made genetic” after 1960, with the long-term aim of treating and curing them using gene therapy. In the process, he explains, these disorders were located in the human genome and became targets for prenatal prevention, while the ongoing promise of gene therapy remained on the distant horizon. In narrating the history of research that contributed to diagnostic genetic medicine, Hogan describes the expanding scope of prenatal diagnosis and prevention. He draws on case studies of Prader-Willi, fragile X, DiGeorge, and velo-cardio-facial syndromes to illustrate that almost all testing in medical genetics is inseparable from the larger—and increasingly “big data”–oriented—aims of biomedical research. Hogan also reveals how contemporary genetic testing infrastructure reflects an intense collaboration among cytogeneticists, molecular biologists, and doctors specializing in human malformation. Hogan critiques the modern ideology of genetic prevention, which suggests all pregnancies are at risk for genetic disease and should be subject to extensive genomic screening. He examines the dilemmas and ethics of the use of prenatal diagnostic information in an era when medical geneticists and biotechnology companies offer whole genome prenatal screening—essentially searching for any disease-causing mutation. Hogan’s analysis is animated by ongoing scientific and scholarly debates about the extent to which the preventive focus in contemporary medical genetics resembles the aims of earlier eugenicists. Written for historians, sociologists, and anthropologists of science and medicine, as well as bioethics scholars, physicians, geneticists, and families affected by genetic conditions, Life Histories of Genetic Disease is a profound exploration of the scientific culture surrounding malformation and mutation.

A history of genetic testing warns that such tests may tell us more than we want to know. Medical geneticists began mapping the chromosomal infrastructure piece by piece in the 1970s by focusing on what was known about individual genetic disorders. Five decades later, their infrastructure had become an edifice for prevention, allowing today’s expecting parents to choose to test prenatally for hundreds of disease-specific mutations using powerful genetic testing platforms.

Duchenne Muscular Dystrophy is a disease that only affects males, with an incidence of around 1 in 3500 new-born baby boys. Its relentless progress is charterized by loss of the ability to walk by around the age of 10 or 11, leading to a wheelchair life, and dealth from cardiac and respiratory problems usually around the late teens or early twenties. Edward Meryon was the first person to give a full and detailed clinical description of what later research knows as Duchenne Muscular Dystrophy. His research identified many facets of the condition which we now take for granted, for example that it only affects males, that it is an inherited condition carried in female genes, that it is a disease of the muscle system, and its causes. Until recently, Meryon has not been given credit for his contribution to the subject. In this book, the history of Duchenne Muscular Dystrophy is traced in detail, and is interwoven with a commentary of Meryon's research which has led to our current understanding of the disease, will full refences and informative, historically relevant illustrations. This book concludes with a summary of the current position regarding diagnosis, prevention through counselling and prenatal diagnosis, and new encouraging approaches to treatment through molecular genetics.

"[Kolata] is a gifted storyteller. Her account of the Baxleys... is both engrossing and distressing... Kolata's book raises crucial questions about knowledge that can be both vital and fatal, both pallative and dangerous." —Andrew Solomon, The New York Review of Books New York Times science reporter Gina Kolata follows a family through genetic illness and one courageous daughter who decides her fate shall no longer be decided by a genetic flaw. The phone rings. The doctor from California is on the line. “Are you ready Amanda?” The two people Amanda Baxley loves the most had begged her not to be tested—at least, not now. But she had to find out. If your family carried a mutated gene that foretold a brutal illness and you were offered the chance to find out if you’d inherited it, would you do it? Would you walk toward the problem, bravely accepting whatever answer came your way? Or would you avoid the potential bad news as long as possible? In Mercies in Disguise, acclaimed New York Times science reporter and bestselling author Gina Kolata tells the story of the Baxleys, an almost archetypal family in a small town in South Carolina. A proud and determined clan, many of them doctors, they are struck one by one with an inscrutable illness. They finally discover the cause of the disease after a remarkable sequence of events that many saw as providential. Meanwhile, science, progressing for a half a century along a parallel track, had handed the Baxleys a resolution—not a cure, but a blood test that would reveal who had the gene for the disease and who did not. And science would offer another dilemma—fertility specialists had created a way to spare the children through an expensive process. A work of narrative nonfiction, Mercies in Disguise is the story of a family that took matters into its own hands when the medical world abandoned them. It’s a story of a family that had to deal with unspeakable tragedy and yet did not allow it to tear them apart. And it is the story of a young woman—Amanda Baxley—who faced the future head on, determined to find a way to disrupt her family’s destiny.

How did a disease of marginal public health significance acquire paradigmatic status in public health and genetics? In a lifetime of practice, most physicians will never encounter a single case of PKU. Yet every physician in the industrialized world learns about the disease in medical school and, since the early 1960s, the newborn heel stick test for PKU has been mandatory in many countries. Diane B. Paul and Jeffrey P. Brosco’s beautifully written book explains this paradox. PKU (phenylketonuria) is a genetic disorder that causes severe cognitive impairment if it is not detected and treated with a strict and difficult diet. Programs to detect PKU and start treatment early are deservedly considered a public health success story. Some have traded on this success to urge expanded newborn screening, defend basic research in genetics, and confront proponents of genetic determinism. In this context, treatment for PKU is typically represented as a simple matter of adhering to a low-phenylalanine diet. In reality, the challenges of living with PKU are daunting. In this first general history of PKU, a historian and a pediatrician explore how a rare genetic disease became the object of an unprecedented system for routine testing. The PKU Paradox is informed by interviews with scientists, clinicians, policymakers, and individuals who live with the disease. The questions it raises touch on ongoing controversies about newborn screening and what happens to blood samples collected at birth.

Life histories can be defined as the means by which individuals (or more precisely genotypes) vary their age- or stage-specific expenditures of reproductive effort in response to genetic, phenotypic, and environmental correlates of survival and fecundity. Life histories reflect the expression of traits most closely related to individual fitness, such as age and size at maturity, number and size of offspring, and the timing of the expression of those traits throughout an individual's life. In addition to addressing questions of fundamental importance to ecology and evolution, life-history research plays an integral role in species conservation and management. This accessible primer encompasses the basic concepts, theories, and applied elements of life history evolution, including patterns of trait variability, underlying mechanisms of plastic/evolutionary change, and the practical utility of life-history traits as metrics of species/population recovery, sustainable exploitation, and risk of extinction. Empirical examples are drawn from the entire spectrum of life. A Primer of Life Histories is designed for readers from a broad range of academic backgrounds and experience including graduate students and researchers of ecology and evolutionary biology. It will also be useful to a more applied audience of academic/government researchers in fields such as wildlife biology, conservation biology, fisheries science, and the environmental sciences.

The #1 NEW YORK TIMES Bestseller The basis for the PBS Ken Burns Documentary The Gene: An Intimate History Now includes an excerpt from Siddhartha Mukherjee’s new book Song of the Cell! From the Pulitzer Prize–winning author of The Emperor of All Maladies—a fascinating history of the gene and “a magisterial account of how human minds have laboriously, ingeniously picked apart what makes us tick” (Elle). “Sid Mukherjee has the uncanny ability to bring together science, history, and the future in a way that is understandable and riveting, guiding us through both time and the mystery of life itself.” —Ken Burns “Dr. Siddhartha Mukherjee dazzled readers with his Pulitzer Prize-winning The Emperor of All Maladies in 2010. That achievement was evidently just a warm-up for his virtuoso performance in The Gene: An Intimate History, in which he braids science, history, and memoir into an epic with all the range and biblical thunder of Paradise Lost” (The New York Times). In this biography Mukherjee brings to life the quest to understand human heredity and its surprising influence on our lives, personalities, identities, fates, and choices. “Mukherjee expresses abstract intellectual ideas through emotional stories…[and] swaddles his medical rigor with rhapsodic tenderness, surprising vulnerability, and occasional flashes of pure poetry” (The Washington Post). Throughout, the story of Mukherjee’s own family—with its tragic and bewildering history of mental illness—reminds us of the questions that hang over our ability to translate the science of genetics from the laboratory to the real world. In riveting and dramatic prose, he describes the centuries of research and experimentation—from Aristotle and Pythagoras to Mendel and Darwin, from Boveri and Morgan to Crick, Watson and Franklin, all the way through the revolutionary twenty-first century innovators who mapped the human genome. “A fascinating and often sobering history of how humans came to understand the roles of genes in making us who we are—and what our manipulation of those genes might mean for our future” (Milwaukee Journal-Sentinel), The Gene is the revelatory and magisterial history of a scientific idea coming to life, the most crucial science of our time, intimately explained by a master. “The Gene is a book we all should read” (USA TODAY).
