Book excerpt: World of Unstable Mutations The book "Triplet Repeat Diseases of the Nervous System" overviews the lat est data on several disorders associated with unstable mutations. This field of re search is progressing extremely fast. The number of polymorphic mutations and diseases caused by these mutations is increasing almost every month. There is a strong interest to molecular bases of triplet repeat disorders. This is explained by growing necessity to develop molecular approaches for cure of these diseases. There fore, the authors of this book describe unstable mutations with the emphasis on molecular pathology. Broad discussion is presented on how polymorphic expan sions cause cell dysfunction. o The first chapter of the book focuses on the molecular pathological pro cesses that originate "unstable" mutations. The authors review several avail able models by which normal "stable" region of DNA become pathogenic and discuss possible mechanisms causing DNA instability. o The other chapters of the book describe inherited diseases associated with different types of unstable mutations. Based on the location of mutation in the disease gene, polymorphic expansions of the nervous system can be divided into two major groups. First group includes disorders with unstable expansions within the open reading frame of the gene such as Spinocer ebellar Ataxias caused by polyglutamine expansions. The second group in cludes diseases caused by expansions situated within the untranslated re gions of the gene.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2013-06-05 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Till recently, mutations in genes were described in textbooks as deletions or point mutations. These mutations can be inherited from a parent or they are de novo alterations. The discovery in 1991 that human disease can be caused by large-scale ex pansion of highly unstable trinucleotide repeats has elucidated a new mutation mechanism, heritable unstable DNA. In the subsequent years more then 10 such disease genes have been identified. All dynamic mutations have been iden tified in neurological disorders. There are ten possible trinucleotide repeats at the DNA level, but only 3 have been identified as being involved in human dis eases. The rather frequent occurence of triplet repeats in the human genome indicates that other loci subject to unstable expansions may be discovered. The identification of repeat instability and the identification of disease genes containing trinucleotide repeats has helped to answer intriguing questions. The diseases share the unusual characteristic of inheritance with increased disease severity in successive gernerations, a phenomenon called anticipation. Trinu cleotide repeat diseases are ideal subjects for direct testing because the muta tion is almost exclusively of the same type and there is an extremely low occur ance of new mutations in these diseases. The anticipation can now be explained by the correlation of increasing repeat length with increased disease serverity. It can be speculated that other neurological disorders showing anticipation will be caused by unstable repeats as well.

Download or read book Inherited Ataxias written by A. E. Harding and published by Lippincott Williams & Wilkins. This book was released on 1993 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this volume, more than 50 leading international experts review the latest scientific and clinical observations on inherited ataxias. The book demonstrates how molecular genetic studies, as well as recent physiological, neurochemical, and clinical data, have generated new concepts on the nosology of these disorders. Close attention is given to the important practical applications of these new findings - in diagnosis, prognosis, and genetic counseling, in development of tests for prenatal diagnosis and carrier detection, and in the search for more effective therapies. The opening chapter identifies the clinical features that distinguish the various inherited ataxic syndromes and presents a classification based on etiology, mode of inheritance, age of onset, and associated clinical features. A major portion of the book focuses on current clinical and molecular genetic studies of different forms of inherited ataxia. Coverage includes a molecular analysis of the Friedreich's ataxia locus and extensive studies on autosomal recessive spastic ataxia of Charlevoix-Saguenay, ataxia telangiectasia, dominantly inherited spinocerebellar ataxias, Machado-Joseph disease, and inherited prion diseases. The contributors provide detailed information on the various clinical phenotypes of each form of inherited ataxia and thoroughly explain the use of linkage analysis and other molecular genetic techniques to localize and isolate the genes responsible for these diseases. The book also reviews the most significant research findings on neurotransmitters in the cerebellum, on the phosphoinositide second messenger system in cerebellar degenerative disorders, and on oligodendrocyte-associated andmyelin-associated inhibitors of neurite growth in the adult nervous system. The contributors assess recent progress in developing drugs for treatment of ataxias and other cerebellar movement disorders and identify new targets for pharmacological intervention. Experimental therapeutic observations on cerebellar grafting in heredodegenerative ataxia are also presented. This volume is an invaluable reference for clinicians treating patients with ataxias or counseling families at risk for inherited neurological diseases. It is also a rich source of ideas for molecular geneticists and for neuroscientists investigating disorders of the cerebellum.

Download or read book Polyglutamine Disorders written by Clévio Nóbrega and published by Springer. This book was released on 2018-02-09 with total page 469 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a cutting-edge review of polyglutamine disorders. It primarily focuses on two main aspects: (1) the mechanisms underlying the pathologies’ development and progression, and (2) the therapeutic strategies that are currently being explored to stop or delay disease progression. Polyglutamine (polyQ) disorders are a group of inherited neurodegenerative diseases with a fatal outcome that are caused by an abnormal expansion of a coding trinucleotide repeat (CAG), which is then translated in an abnormal protein with an elongated glutamine tract (Q). To date, nine polyQ disorders have been identified and described: dentatorubral-pallidoluysian atrophy (DRPLA); Huntington’s disease (HD); spinal–bulbar muscular atrophy (SBMA); and six spinocerebellar ataxias (SCA 1, 2, 3, 6, 7, and 17). The genetic basis of polyQ disorders is well established and described, and despite important advances that have opened up the possibility of generating genetic models of the disease, the mechanisms that cause neuronal degeneration are still largely unknown and there is currently no treatment available for these disorders. Further, it is believed that the different polyQ may share some mechanisms and pathways contributing to neurodegeneration and disease progression.
