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.
A grand summary and synthesis of the tremendous amount of data now available in the post genomic era on the structural features, architecture, and evolution of the human genome. The authors demonstrate how such architectural features may be important to both evolution and to explaining the susceptibility to those DNA rearrangements associated with disease. Technologies to assay for such structural variation of the human genome and to model genomic disorders in mice are also presented. Two appendices detail the genomic disorders, providing genomic features at the locus undergoing rearrangement, their clinical features, and frequency of detection.
Pompe disease, also known as acid maltase deficiency or acid alpha-glucosidase deficiency, in its most severe form results in a rapidly progressive, neonatal-onset skeletal and cardiomyopathy, leading to early infantile death without treatment. The development of treatment with recombinant enzyme replacement therapy radically transformed the clinical trajectory of those affected, enabling long-term ventilator-free survival with resolution of cardiomyopathy. These positive clinical outcomes resulted in the implementation of newborn screening programs for Pompe disease across the world. This Special Issue highlights some of the experiences of Pompe screening programs worldwide and discusses public policy and ethical issues elicited by presymptomatic screening for Pompe disease.
A sharp-eyed exploration of the promise and peril of having children in an age of genetic tests and interventions Is screening for disease in an embryo a humane form of family planning or a slippery slope toward eugenics? Should doctors tell you that your infant daughter is genetically predisposed to breast cancer? If tests revealed that your toddler has a genetic mutation whose significance isn’t clear, would you want to know? In The Gene Machine, the award-winning journalist Bonnie Rochman deftly explores these hot-button questions, guiding us through the new frontier of gene technology and how it is transforming medicine, bioethics, health care, and the factors that shape a family. Rochman tells the stories of scientists working to unlock the secrets of the human genome; genetic counselors and spiritual advisers guiding mothers and fathers through life-changing choices; and, of course, parents (including Rochman herself) grappling with revelations that are sometimes joyous, sometimes heartbreaking, but always profound. She navigates the dizzying and constantly expanding array of prenatal and postnatal tests, from carrier screening to genome sequencing, while considering how access to more tests is altering perceptions of disability and changing the conversation about what sort of life is worth living and who draws the line. Along the way, she highlights the most urgent ethical quandary: Is this technology a triumph of modern medicine or a Pandora’s box of possibilities? Propelled by human narratives and meticulously reported, The Gene Machine is both a scientific road map and a meditation on our power to shape the future. It is a book that gets to the very core of what it means to be human.
Volume 1 of the Prevention Book presents the principles of a programme for the prevention of the thalassaemia and other haemoglobin disorders, including a description of the various types of disorders requiring prenatal diagnosis, the strategies used for carrier screening, and a number of annexes listing upto date epidemiological and mutation data on thalassaemia. This book was written for use in combination with Volume 2, which describes many of the laboratory protocols in great detail.
This text offers current thinking in the field. The authors are well-established qualitative researchers and have pulled off a great text for the beginning researcher.
As mass spectrometric methods now offer a level of specificity and sensitivity unrealized by spectrophotometric- and immunoassay-based methods, mass spectrometry has entered the clinical laboratory where it is being used for a wide range of applications. In Clinical Applications of Mass Spectrometry: Methods and Protocols, expert researchers provide detailed step-by-step procedures for the analysis of number of analytes of clinical importance. This versatile and expansive volume covers mass spectrometry methods for analytes including a variety of drugs, hormones, and metabolic compounds spanning the disciplines of toxicology, therapeutic drug monitoring, endocrinology, and pediatric metabolism. Written in the highly successful Methods in Molecular BiologyTM series format, chapters include brief introductions to the analytes, lists of the necessary materials and reagents, readily reproducible analytical protocols, and detailed notes on troubleshooting and avoiding known pitfalls. Comprehensive and dependable, Clinical Applications of Mass Spectrometry: Methods and Protocols offers its readers a wide array of valuable methods for experienced mass spectrometric labs that are looking to introduce new analyses as well as for those laboratories currently considering the addition of this resourceful and vital technology.
