The Molecular Biology of Down Syndrome


Book Description

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.




Molecular Genetics of Chromosome 21 and Down Syndrome


Book Description

In recent years, the molecular analysis of chromosome 21 has progressed so rapidly that the current level of sophistication in understanding the organization of its genes and DNA sequences perhaps exceeds that of any other chromosome. This book explores the fundamental nature of this condition's pathology as related to the structure and expression of genes that are known to be critical in the development of Down Syndrome. It recounts the impressive advances made toward a complete physical mapping of chromosome 21. It also discusses how individual genes in this chromosome have been isolated and their effects relevant to aspects of Down Syndrome are being studied in both cellular and in vivo models. This text provides a comprehensive account of the most up-to-date research in this area, and offers a general overview of the advances in molecular analysis techniques that are revolutionizing the entire field of chromosomal mapping.

Down Syndrome: From Understanding the Neurobiology to Therapy


Book Description

Down syndrome (DS) is the most common example of neurogenetic aneuploid disorder leading to mental retardation. In most cases, DS results from an extra copy of chromosome 21 (HSA21) producing deregulated gene expression in brain that gives raise to subnormal intellectual functioning. The topic of this volume is of broad interest for the neuroscience community, because it tackles the concept of neurogenomics, that is, how the genome as a whole contributes to a neurodevelopmental cognitive disorders, such as DS, and thus to the development, structure and function of the nervous system. This volume of Progress in Brain Research discusses comparative genomics, gene expression atlases of the brain, network genetics, engineered mouse models and applications to human and mouse behavioral and cognitive phenotypes. It brings together scientists of diverse backgrounds, by facilitating the integration of research directed at different levels of biological organization, and by highlighting translational research and the application of the existing scientific knowledge to develop improved DS treatments and cures. - Leading authors review the state-of-the-art in their field of investigation and provide their views and perspectives for future research - Chapters are extensively referenced to provide readers with a comprehensive list of resources on the topics covered - All chapters include comprehensive background information and are written in a clear form that is also accessible to the non-specialist







Phenotypic Mapping of Down Syndrome


Book Description

Progress in Clinical and Biological Research, Volume 384 The Phenotypic Mapping of Down Syndrome and Other Aneuploid Conditions Proceedings of a National Down Syndrome Society Conference Held in New York, January 14 and 15, 1993 Charles J. Epstein, Editor In the last decade, considerable progress in the phenotypic mapping of Down syndrome and other syndromes caused by aneuploidy has been made, answering many perplexing questions and raising new ones. Of primary concern is the relationship between the individual components of the Down syndrome phenotype and the specific genes that give rise to them. In its continuing role of supporting basic research through scientific conferences, the National Down Syndrome Society brought together a panel of experts from genetics, molecular, and cellular biology to explore the genotype—phenotype correlations of Down syndrome and other aneuploid conditions. The Phenotypic Mapping of Down Syndrome and Other Aneuploid Conditions discusses approaches to understanding the genetics and the underlying mechanisms of the different phenotypic characteristics of Down syndrome, as well as animal models of trisomy 21 relevant to phenotypic mapping of Down syndrome. Since the precedents for phenotypic mapping go far beyond human chromosome 21, the book also covers several other aneuploid states in addition to Down syndrome itself, thereby presenting the latest information about state-of-the-art approaches to phenotypic mapping. The text is divided into the following sections: General Approach to Phenotypic Mapping in Aneuploidy Phenotypic Mapping of Down Syndrome Phenotypic Mapping of Animal Models Phenotypic Mapping in Conditions Other than Trisomy 21 The Phenotypic Mapping of Down Syndrome and Other Aneuploid Conditions is essential reading for medical and human geneticists as well as other scientists working in the fields of Down syndrome and related conditions. In addition, clinicians caring for individuals with Down syndrome and other syndromes resulting from aneuploidy will find this book of interest.







Focus on Medical Genetics and Down's Syndrome Research


Book Description

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.




Down Syndrome


Book Description

Down syndrome, the most cutting-edge book in the field congenital disorders. This book features up-to-date, well referenced research and review articles on Down syndrome. Research workers, scientists, medical graduates and pediatricians will find it to be an excellent source for references and review. It is hoped that such individuals will view this book as a resource that can be consulted during all stages of their research and clinical investigations. Key features of this book are: Common diseases in Down syndrome Molecular Genetics Neurological Disorders Prenatal Diagnosis and Genetic Counselling Whilst aimed primarily at research workers on Down syndrome, we hope that the appeal of this book will extend beyond the narrow confines of academic interest and be of interest to a wider audience, especially parents, relatives and health-care providers who work with infants and children with Down syndrome.
