"This book traces the development of genetics in medicine from the first descriptions of inherited diseases more than 300 years ago to the new applications resulting from mapping and sequencing the human genome. It follows both the scientific and the medical advances, focusing especially on those of the past 50 years, which have seen the field of medical genetics emerge as one of the foremost and most rapidly changing medical specialties, now influencing the whole of medicine. It also examines the ethical challenges faced by those working in the field, and describes some of the past disasters that have resulted from these being ignored, notably the abuses of eugenics and the catastrophic destruction of genetics in Soviet Russia. This is the first book of its kind; it is clearly and simply written, and will be valuable to all those who have an interest or concern in the development of medical genetics, as well as those actually working in the field. Historians and social scientists will likewise find this book an important foundation for future detailed studies, which are urgently needed."--BOOK JACKET.
