The advent of human in vitro fertilization and developments in molecular science have made it possible to diagnose genetic disease in fetuses at a very early stage of development. This book presents the most recent advances and developments in this new area of applied research. Experts in the field describe and discuss the latest technology, from micromanipulation of single cells to sophisticated methods of DNA analysis. The book considers the implications of this new technology for fetal screening and the prevention of genetic disease, as well as for the control and manipulation of the normal sex ratio. It draws together current knowledge and discusses the new clinical opportunities for disease prevention. The book begins with an overview of the genetics of some common inherited diseases and the historical development of prenatal screening. It then draws together the most recent advances in preimplantation diagnostic techniques, including tissue assays for specific genetic disorders, and methods for typing and separating spermatozoa. The practical aspects of the new methodologies are considered, along with the potential for developing safer, more reliable and less invasive methods of diagnosis. The ethical and legal implications of this diagnostic approach are also discussed.

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.

Preimplantation Genetic Diagnosis (PGD) is the detection and screening of genetic abnormality in gametes prior to fertilisation and embryos fertilised in vitro prior to implantation. This exciting new text provides an introduction and overview of the principles of PGD. An exciting fusion of prenatal diagnosis (PD) with in vitro fertilisation (IVF), this book is will appeal to both the prenatal diagnosis community, of clinical geneticists and foetal medicine specialists within obstetrics and gynaecology, and the IVF community within reproductive medicine. It is also an essential introduction to PD, clinical genetics and IVF for non-specialists. A concise introduction to the field of PGD Detailed explanations of the techniques and procedures used The law and ethical implications of PGD Future uses of PGD

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.

This book presents the findings of the RCOG Study Group findings on genetics underlying reproductive function.

Yury Verlinskyand Anver Kuliev Reproductive Genetics Institute, Illinois Masonic Medical Center, 836 W. Wellington chicago, IL 60657 Although introduction of a first trimester prenatal diagnosis by chorionic viIIus sampling (CVS) has considerably improved the possibility for prevention of genetic diseases, it requires a selective abortion in case of an affected fetus. Following the direction of an earlier prenatal diagnosis and to avoid the need for abortion, preimplantation genetic diagnosis has been initiated based on polar body removal and pre-embryo biopsy. The First International symposium on Preimplantation Genetics, Chicago, September 17-19, 1990, was organized to explore these important developments, to review the state of knowledge in the field, and to address existing problems to be solved for developing and improving current approaches for preimplantation diagnosis of genetic disorders. A growing interest in the subject was obvious from the wide attendance of the meeting: over 250 scientists from 19 countries participated. This was the first attempt to put together the advances in different areas of basic and applied research relevant to Preimplantation Genetic Diagnosis, with the multidisciplinary scientific program including the sessions on embryology, micromanipulation and biopsy, genetic analysis of gametes and pre-embryos, IVF, gene expression and gene therapy, and ethical and legal issues. The deliberations of the Symposium presented in the above mentioned sessions, which comprise the contents of correspond ing sections of the Proceedings, open a newarea in medical research based on the interaction of IVF and New Genetics.

This book aims to expand the awareness and understanding of the emotional sequelae of prenatal/preimplantation diagnosis, prenatal decision-making, pregnancy interruption for fetal anomaly, multifetal reduction for high-order multifetal pregnancies and preimplantation choices involving the selection of embryos. Featuring a multi-disciplinary approach, it examines prenatal and preimplantation diagnosis from medical, legal, ethical and psychosocial perspectives. Prenatal and Preimplantation Diagnosis is an excellent resource for obstetricians, reproductive endocrinologists, clinical geneticists, genetic counselors and mental health professionals seeking to better support patients faced with difficult choices.
