Genetic Testing

Over the last decade, technical advances have allowed genomic testing which provides a great opportunity for diagnosis but also an increased chance of uncertain or unexpected findings. This book addresses many of the questions that arise in this context and summarizes the essential concepts in diagnostic genetic testing in an easy-to-read manner. It also covers some broad context for the practical and ethical implications of examining human DNA sequences. The book starts with a general introduction to the field, providing enough background to allow readers without any previous education in genetics to comprehend the material in the subsequent chapters. The main part explores differing aspects of human genetics and the wider implications of testing in these areas. The author covers not only single gene inheritance, but also genetic testing of cancers and how testing benefits the patients. Special emphasis is also given to the questions of genetics and identity. The concluding part then draws the main themes together and summarises the wider significance of genetics. It also explores the gap between promises made for the impact of advances in genetics, and the actual benefits to patients. The book is written for everyone interested to learn about the process of genetic testing and the broader implications. Moreover, it is aimed at health professionals with an interest in genetics, at students or scientific trainees looking for an introduction to diagnostic genetics, and at professionals in health policy or health journalism.

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.

In this volume, the psychiatrist Robert Klitzman explores how individuals confront the complex issues associated with genetic testing in their daily lives.

Advances in genetics and genomics are transforming medical practice, resulting in a dramatic growth of genetic testing in the health care system. The rapid development of new technologies, however, has also brought challenges, including the need for rigorous evaluation of the validity and utility of genetic tests, questions regarding the best ways to incorporate them into medical practice, and how to weigh their cost against potential short- and long-term benefits. As the availability of genetic tests increases so do concerns about the achievement of meaningful improvements in clinical outcomes, costs of testing, and the potential for accentuating medical care inequality. Given the rapid pace in the development of genetic tests and new testing technologies, An Evidence Framework for Genetic Testing seeks to advance the development of an adequate evidence base for genetic tests to improve patient care and treatment. Additionally, this report recommends a framework for decision-making regarding the use of genetic tests in clinical care.

This book addresses emerging questions concerning who should bear responsibility for shouldering risk, as well as the viability of existing and experimental governance mechanisms in connection with new technologies. Scholars from 14 jurisdictions unite their efforts in this edited collection to provide a comparative analysis of how various legal systems are tackling the challenges produced by the legal aspects of genetic testing in insurance and employment. They cover the diverse set of norms that surround this issue, and share insights into relevant international, regional and national incursions into the field. By doing so, the authors offer a basis for comparative reflection, including on whether transnational standard setting might be useful or necessary for the legal aspects of genetic testing as they relate to the insurance and employment contexts. The respective texts cover a broad range of topics, including the prevalence of genetic testing in the contexts of insurance and employment, and policy factors that might affect this prevalence, such as the design of national health or social insurance systems, of private insurance schemes or the availability of low-cost direct-to-consumer genetic testing. Further, the field of genetics is gaining in importance at the international and regional levels. Relevant concepts – mainly genetic tests and genetic data/information – have been internationally defined, and these definitions have influenced definitions adopted nationally. International law also recognizes a “special status” for human genetic data. The authors therefore also consider these definitions and the recognition of the special status of human genetic data within regional and national legal orders. They investigate the range of norms that specifically address the use of genetic testing in employment and insurance, encompassing international sources – including human rights norms – that may be binding or non-binding, as well national statutory, regulatory and soft-law mechanisms. Accordingly, some of the texts examine general frameworks relevant to genetic testing in each country, including those that stem from general anti-discrimination rules and norms protecting rights to autonomy, self-determination, confidentiality and privacy. In closing, the authors provide an overview of the efficiency of their respective legal regimes’ approaches – specific and generalist – to genetic testing or disclosure of genetic information in the employment or insurance contexts, including the effect of lack of legal guidance. In this regard, some of the authors highlight the need for transnational action in the field and make recommendation for future legal developments.

An invaluable student-tested study aid, this primer, first published in 2007, provides guided instruction for the analysis and interpretation of genetic principles and practice in problem solving. Each section is introduced with a summary of useful hints for problem solving and an overview of the topic with key terms. A series of problems, generally progressing from simple to more complex, then allows students to test their understanding of the material. Each question and answer is accompanied by detailed explanation. This third edition includes additional problems in basic areas that often challenge students, extended coverage in molecular biology and development, an expanded glossary of terms, and updated historical landmarks. Students at all levels, from beginning biologists and premedical students to graduates seeking a review of basic genetics, will find this book a valuable aid. It will complement the formal presentation in any genetics textbook or stand alone as a self-paced review manual.

Preimplantation genetic testing (PGT) is now well established as a valuable treatment option for patients wishing to start or continue a family, for a range of indications from advanced maternal age to high risk of transmitting inherited disease. This text brings together contemporary thinking from international opinion leaders and will be an invaluable guide for practitioners in Reproductive Medicine wishing to keep pace with the latest developments and clinical data.
