Prenatal Diagnosis


Book Description

This second edition volume expands on the first edition with more detailed methodologies on prenatal testing and diagnosis, and also covers next-generation sequencing techniques. The chapters in this book are divided into three sections: preimplantation genetic testing, traditional prenatal testing, and non-invasive prenatal testing. This book covers topics such as molecular testing for preimplantation genetic diagnosis of single gene disorders; DNA extraction from various types of prenatal specimens; prenatal diagnosis of cystic fibrosis and Tay-Sachs disease; chromosomal SNP microarrays; and isolation of cell-free DNA from maternal plasma. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Practical and thorough, Prenatal Diagnosis, Second Edition is a valuable resource for any researcher interested in reproducing these techniques in their clinical laboratories.




Noninvasive Prenatal Testing (NIPT)


Book Description

Since its introduction in 2012, cell-free (cf) DNA based Non-Invasive Prenatal Testing (NIPT) has been employed to test for fetal chromosome abnormalities, and gene mutations that lead to a variety of genetic conditions, by millions of pregnant women, in more than 90 countries worldwide. With Noninvasive Prenatal Testing (NIPT): Applied Genomics in Prenatal Screening and Diagnosis, Dr Lieve Page-Christiaens and Dr Hanns-Georg Klein have compiled the first authoritative volume on cfDNA NIPT methods and their clinical implementation. - Provides a thorough, practical examination of the history of NIPT, NIPT laboratory techniques and bioinformatics, NIPT screening and diagnostics for a wide range of disorders and birth defects - Presents leading, international experts who discuss the application of NIPT in early screening for common aneuploidies, fetal chromosome anomalies, autosomal trisomies, fetal blood group typing, and maternal constitutional and acquired copy number variants - Includes full color imagery that enhances concept illustration, along with detailed descriptions of the benefits (and limitations) of NIPT - Offers clinicians, researchers, genetic counselors and reproductive specialists of all kinds the required background information, methodologies and essential patient counseling techniques




Prenatal Testing and Disability Rights


Book Description

As prenatal tests proliferate, the medical and broader communities perceive that such testing is a logical extension of good prenatal care—it helps parents have healthy babies. But prenatal tests have been criticized by the disability rights community, which contends that advances in science should be directed at improving their lives, not preventing them. Used primarily to decide to abort a fetus that would have been born with mental or physical impairments, prenatal tests arguably reinforce discrimination against and misconceptions about people with disabilities. In these essays, people on both sides of the issue engage in an honest and occasionally painful debate about prenatal testing and selective abortion. The contributors include both people who live with and people who theorize about disabilities, scholars from the social sciences and humanities, medical geneticists, genetic counselors, physicians, and lawyers. Although the essayists don't arrive at a consensus over the disability community's objections to prenatal testing and its consequences, they do offer recommendations for ameliorating some of the problems associated with the practice.




3D Ultrasound in Prenatal Diagnosis


Book Description

Initially known for its beautiful images of the faces of babies, 3D ultrasound has, however, become an important tool in prenatal diagnosis for its ability to image fetal organs in normal and abnormal conditions. This book is a state-of-the-art work conceived as a practical guide to the application of 3D ultrasound in obstetrics. The authors of this book have extensive expertise in 3D ultrasound that spans for more than 25 years. The book has three sections: one section on the technical principles of 3D ultrasound, a second section on various 3D rendering tools with a step-by-step explanation of its use. The third section is dedicated to the clinical use of 3D in the examination of the fetal organs. In this 2nd edition, the entire book has been revised and actualized.




Ethical Dilemmas in Prenatal Diagnosis


Book Description

Technological developments in the life sciences confront us with new facets of a Faustian seduction. Are we „playing God“ more and more, as claimed by critical authors of modernity? Achievements in genetic research produce ethical dilemmas which need to be the subject of reflection and debate in modern societies. Denial of ambivalences that ethical dilemmas arouse constitutes a threat to societies as well as to individuals. The book presents a compilation of some of the results of the interdisciplinary European study “Ethical Dilemmas Due to Prenatal and Genetic Diagnostics” (EDIG), which investigated some of these dilemmas in detail in a field which is particularly challenging: prenatal diagnosis. When results from prenatal diagnosis show fetal abnormalities, women and their partners are confronted with ethical dilemmas regarding: the right to know and the right not to know; decision-making about the remainder of the pregnancy and the desire for a healthy child; responsibility for the unborn child, for its well-being and possible suffering; life and death. This book provides answers from an ethical, psychoanalytical and medical viewpoint.

Assessing Genetic Risks


Book Description

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.




Genetic Disorders, Syndromology and Prenatal Diagnosis


Book Description

Birth defects have assumed an importance even greater now than in the past because infant mortality rates attributed to congenital anomalies have declined far less than those for other causes of death, such as infectious and nutritional diseases. As many as 50 % of all pregnancies terminate as miscarriages, and in the majority of cases this is the result of faulty intrauterine development. Major congenital malformations are present in at least 2 % of all liveborn infants, and 22 % of all stillbirths and infant deaths are associated with severe congenital anomalies. Not surprisingly, there has been a great proliferation of research into the problems of developmental abnormalities over the past few decades. This series, Advances in the Study of Birth Defects, was conceived in order to provide a comprehensive focal source of up-to-date information for physi cians concerned with the health of the unborn child and for research workers in the fields of fetal medicine and birth defects. The first four volumes featured recent experimental work on selected areas of high priority and intensive investigation, including mechanisms of teratogenesis, teratological evaluation, molecular and cellular aspects of abnormal development, and neural and behavioural teratology. It seems logical and timely that the clinical aspects should now be presented. Accordingly, leading experts were invited to review a broad range of common problems from the standpoint of embryology, aetiology, clinical manifestations, diagnosis and management. This volume deals with genetic disorders and prenatal diagnosis.
