Medical Genetics is the application of genetics to medicine. Medical genetics is broad and varied and encompasses many different individual fields, including clinical genetics, biochemical genetics, cytogenetics, molecular genetics, the genetics of common diseases (such as neural tube defects), and genetic counselling. Each of the individual fields within medical genetics is a hybrid. Clinical genetics is a hybrid of clinical medicine with genetics. Biochemical genetics is a hybrid of biochemistry, mainly the biochemistry of amino acids and proteins, with genetics. Molecular genetics is a hybrid of the biochemistry of DNA and RNA with genetics. Cytogenetics is a hybrid of cytology and genetics; it involves the study of chromosomes under the microscope. And genetic counselling is a hybrid of genetics with non-directional counselling. This book presents leading-edge research on medical genetics as well as on Down's syndrome.

This book provides a concise yet comprehensive source of current information on Down syndrome. It focuses on exciting areas of research on chromosome editing, neurogenomics and diseases associated with Down syndrome. Research workers, scientists, medical graduates and physicians will find this book as an excellent source for consultation and references. Key features of this book are chromosome engineering in Down syndrome, mental retardation and cognitive disability, prenatal diagnosis and diseases associated with Down syndrome. Although aimed primarily for research workers on Down syndrome, we hope that the appeal of this book will extend beyond the narrow confines of academic interest and be exciting to wider audience, especially parents, relatives and health care providers who work with infants and children with Down syndrome.

Even the closest brothers and sisters don't always get along or understand each other. Add a disability like Down syndrome to the mix, and that sibling relationship gets even more complicated, especially for teenagers. Fasten Your Seatbelt is the first book written exclusively for teens with a brother or sister with Down syndrome. In an easy-to-read, question & answer format, it tackles a broad range of their most common issues and concerns. Nearly 100 questions--all posed by teen siblings--are grouped into the following categories: Facts and stats about Down syndrome How people with Down syndrome learn Handling parent and family conflicts Dealing with your sibling's frustrating behaviors Managing uncomfortable situations Sorting out your feelings Becoming an advocate What the future holds for you and your sibling Finding local and national resources Thoughtful, knowledgeable answers are provided by Brian Skotko, the brother of a young woman with Down syndrome, and Sue Levine, a social worker focused on sibling issues for the past 30 years. Fasten Your Seatbelt gives teens the green light to explore their own feelings and questions about their sibling with Down syndrome and how their relationship may change in the future. Wondering whats on their minds? Here are a few sample questions from the book: Why does my brother always have temper tantrums? How can one extra chromosome make someone so different? Can my sister with Down syndrome marry someday? Will my brother be able to live on his own as an adult?

This book contains updated reviews and original research work on Down Syndrome focussing on brandnew results in neurobiology, in particular results on gene hunting (subtractive hybridization, differential display) and neurochemistry. The book provides new data such as a subtractive library of Down Syndrome brain showing cDNAs that are overexpressed or downregulated and can be regarded as a source for further research on the preliminary transcriptional data given. A 2D-electrophoretic map of human brain proteins including Down Syndrome brain protein expression established by in-gel-digestion of spots with subsequent MALDI-identification provides the scientific basis for protein work to the neuroscientist. Altogether, the book provides a series of new candidate genes possibly involved in Down Syndrome neurobiology, tools for neuroscience studies on Down Syndrome brain thus serving as a manual and updated views and aspects on Down Syndrome pathobiology.

The Neurobiology of Aging and Alzheimer Disease in Down Syndrome provides a multidisciplinary approach to the understanding of aging and Alzheimer disease in Down syndrome that is synergistic and focused on efforts to understand the neurobiology as it pertains to interventions that will slow or prevent disease. The book provides detailed knowledge of key molecular aspects of aging and neurodegeneration in Down Syndrome by bringing together different models of the diseases and highlighting multiple techniques. Additionally, it includes case studies and coverage of neuroimaging, neuropathological and biomarker changes associated with these cohorts. This is a must-have resource for researchers who work with or study aging and Alzheimer disease either in the general population or in people with Down syndrome, for academic and general physicians who interact with sporadic dementia patients and need more information about Down syndrome, and for new investigators to the aging and Alzheimer/Down syndrome arena. - Discusses the complexities involved with aging and Alzheimer's disease in Down syndrome - Summarizes the neurobiology of aging that requires management in adults with DS and leads to healthier aging and better quality of life into old age - Serves as learning tool to orient researchers to the key challenges and offers insights to help establish critical areas of need for further research

Increasing interest over recent years in the study of the influences of environment and genetic factors on behavioural disorder has come from a wide range of disciplines. These studies have subsequently been focused through the foundation of the Society for the Study of Behavioural Phenotypes, which forms the basis for assimilating new information and coordinating future research in this field. This volume from founder members of the society presents a distillation of thinking and reviews appropriate measurement schedules. Including research findings, explanation of concepts, genetic scientific techniques and methodological issues, this work will be welcomed by those with an interest in behavioural disorder at every level.
