Book Description
Trinucleotide repeats are relatively common in the human genome. These simple repeats have received much attention since epoch-making discoveries were made that particular trinucleotide repeats are expanded in the causal genes of human hereditary neurological disorders. For example, the CGG repeat is expanded in fragile X syndrome at the 5' untranslated region (UTR) of its causal gene. In myotonic dystrophy, it is the CTG repeat that is expanded at the 3' UTR of its causal gene. The CAG repeat was also found expanded in coding regions of the genes responsible for X-linked spinal and bulbar muscular atrophy, Huntington’s disease, spinocerebellar ataxia, and other disorders. On the other hand, expansion of the GAA repeat was identified in the intron of the gene responsible for the Friedreich’s ataxia. For these trinucleotide repeat diseases, the longer the trinucleotide expansion, the earlier the age of onset and the more severe the syndrome. Thus, these findings that showed the intriguing link between a particular trinucleotide expansion and its associated neurological disorders have led to a new field of intensive study. Active research addressing the underlying mechanisms for trinucleotide repeat diseases has employed various approaches ranging from DNA biochemistry to animal models for the diseases. In particular, animal models for the triplet repeat diseases have provided excellent resources not only for understanding the mechanisms but also for exploring therapeutic interventions.

Book Description
There have been remarkable advances towards discovering agents that exhibit selectivity and sequence-specificity for DNA, as well as understanding the interactions that underlie its propensity to bind molecules. This progress has important applications in many areas of biotechnology and medicine, notably in cancer treatment as well as in future gene targeting therapies. The editor and contributing authors are leaders in their fields and provide useful perspectives from diverse and interdisciplinary backgrounds on the current status of this broad area. The role played by chemistry is a unifying theme. Early chapters cover methodologies to evaluate DNA-interactive agents and then the book provides examples of DNA-interactive molecules and technologies in development as therapeutic agents. DNA-binding metal complexes, peptide and polyamide–DNA interactions, and gene targeting tools are some of the most compelling topics treated in depth. This book will be a valuable resource for postgraduate students and researchers in chemical biology, biochemistry, structural biology and medicinal fields. It will also be of interest to supramolecular chemists and biophysicists.

Book Description
This new book is an up-to-date review of the clinical, epidemiological, and cytogenetic aspects of the fragile X (Martin-Bell) syndrome--the most common genetic cause of mental retardation after Down syndrome. The book includes the latest research findings concerning diagnosis on the basis of the appearance of a fragile site in cultured lymphocytes. It assumes little prior knowledge of the subject, and provides a clearly written, easy-to-understand discussion previously unavailable in a single reference source. The book will be of special interest to molecular biologists, cytogeneticists, medical geneticists, and clinicians and other professionals working with the mentally handicapped.

Book Description
This monograph describes the progress in neuropathological HD research made during the last century, the neuropathological hallmarks of HD and their pathogenic relevance. Starting with the initial descriptions of the progressive degeneration of the striatum as one of the key events in HD, the worldwide practiced Vonsattel HD grading system of striatal neurodegeneration will be outlined. Correlating neuropathological data with results on the functional neuroanatomy of the human brain, subsequent chapters will highlight recent HD findings: the neuronal loss in the cerebral neo-and allocortex, the neurodegeneration of select thalamic nuclei, the affection of the cerebellar cortex and nuclei, the involvement of select brainstem nuclei, as well as the pathophysiological relevance of these pathologies for the clinical picture of HD. Finally, the potential pathophysiological role of neuronal huntingtin aggregations and the most important and enduring challenges of neuropathological HD research are discussed.

Book Description
Neurogenetics is intended for any physician or scientist who manages patients with inherited diseases of the nervous system. It presents the clinical phenotypes of the most commonly inherited neurologic diseases, and their molecular pathogenesis, followed by a description of the appropriate tests to be used in diagnosis. Two introductory chapters familiarize the nongeneticist with medical genetic terminology and molecular genetic techniques useful in the analysis of genetic disease and genetic testing. Subsequent chapters examine major neurologic disorders caused by single defects, as well as disease phenotypes such as Alzheimer disease or amyotrophic lateral sclerosis which may be caused by defects in single genes, but may also be seen as sporadic diseases. The genetic components of other common neurologic disorders, such as epilepsy, multiple sclerosis, migraine, and stroke are all covered in detail. The final chapter discusses genetic counseling of symptomatic and pre-symptomatic individuals. Throughout, chapters discuss genotype/phenotype correlations and, where appropriate, animal models for inherited human neurologic diseases. Several chapters are devoted to recently discovered diseases caused by unstable DNA repeats. Special emphasis is placed on conveying how DNA testing can be applied to the daily practice of geneticists and neurologists.
