Chromosome abnormalities occur in about one in a hundred people, and present complex challenges for medical geneticists and genetic counselors. In addition to identifying chromosomal abnormalities, genetics professionals must explain the "unexplainable," helping families understand why chromosome disorders occur and how likely they are to occur again. Chromosome Abnormalities and Genetic Counseling is the definitive guide to navigating chromosome disorders and clinical questions posed by the families they impact. It incorporates the latest advances in molecular technologies and prenatal diagnosis, while also revisiting the classical understanding of chromosomal pathology; the well-known trisomies, deletions, and duplication syndromes; and ways in which these may arise de novo or occur in the setting of a parental chromosome rearrangement. This new edition includes three entirely new chapters on copy number variants, chromosome abnormalities associated with selected phenotypes, and ethical and counseling issues.Completely updated and still infused with the warmth and voice that have made it essential reading for professionals across medical genetics, the 6th edition of Chromosome Abnormalities and Genetic Counseling represents a leap forward in clinical understanding and communication. It is more than just a reference text; it is a holistic guide to thinking about these disorders, even as our technical understanding of them continues to evolve.

Renal genetic disorders may become apparent at any time in life and recognition of specific renal disorders is important in allowing accurate genetic counselling. Active counselling requires knowledge about the natural history of the disorder, an understanding of the genetic component and mode of inheritance, risk of the disorder in other family members, information about patient attitudes towards family planning and the possibility of pre-natal diagnosis.The Genetics of Renal Disease provides a comprehensive account of both the hereditary nephropathies and more generalised disorders, which may affect the renal tract. It includes comprehensive guidelines from an international group of authors on renal function and development, chromosomal disorders, dysmorphic syndromes, inherited predisposition to kidney cancer and gene therapy for renal cancer. Specific chapters deal with individual renal tract disorders such as an extensive discussion of Alport's disease, cystic renal diseases, the Bardet-Biedl and Alstrom syndromes. Each section gives a brief description of the clinical and pathological features of a particular disorder, followed by a review of the genetics of the disorder including incidence, inheritance of familial occurrence, genetic linkage and gene assignment, and prenatal diagnosis and carrier detection. Original studies are extensively quoted and are referenced at the end of each section. There are a great many dysmorphic syndromes that involve the urinary tract. These are incorporated within the book.

When rediscovered at the turn of the century, Mendel's laws were found to be applicable to humans, but from the beginning they were fraught with problems. Sex-linked traits and linked genes defied Mendel's rules. Later, other exceptions were found, including sporadic cases, non-penetrance, variable expressivity, and preferential parental transmission.In this book, Harry Ostrer observes that some of these problems can be explained by incomplete ascertainment, typing errors and modifying genes. He then goes on to systematically explore the evidence for a number of newer genetic processes that were not foreseen by Mendel and his intellectual heirs, examining the molecular basis for these processes and their effects on transmission and phenotype. He shows that these non-Mendelian processes--gonadal and somatic mosaicism, sex-linked inheritance, mitochondrial transmission, genomic imprinting, accelerated rates of mutation, and viral infection--resolve many of the exceptions to Mendelian inheritance. He also provides a complete review of Mendelian genetics, as well as an overview of the structure and functions of genes, chromosomes, and their products. Thus the book presents a holistic view of human genetics.In the last chapter, Ostrer grapples with the possibilities for identifying new genetic processes, and with genetic determinism--the view that a person's phenotype is fully subject to his or her genetic constitution. He contends that despite the large number of genetic combinations, phenotypes cannot be predicted precisely, even with sufficient computing power. Genetic processes are frequently modified by environmental exposure or they may be random or stochastic in their occurrence. Hence, there are innate limits to genetic determinism. Although prediction of phenotype based on genotype will improve in the future as all of the human genes are identified, such predictions will always remain imprecise.

Authoritative clinical reference on genetic sexual disorders, a field that has been transformed in many areas by molecular genetics.

Transcription factors are essential mediators of the genetic programs that control development and physiology. This exciting book presents current knowledge of transcription factors from two viewpoints. First, the basic science of transcriptional regulation is discussed. Second, inherited human diseases attributable to mutations in DNA sequences encoding transcription factors or their cognate binding sites are described. Readers are also introduced to the involvement of transcription factors in somatic cell genetic disease (cancer) and epigenetic disease (teratogenesis).

Psychosocial issues are integral to all genetic counselling interactions. They include counsellees' beliefs about the cause of birth defects and genetic disorders, the cognitive procession of medical information and risk figures, emotions such as anxeity and guilt, and the complex process of decision making. Drawing on direct clinical experience and the growing body of relevant literatue, Psychosocial Genetic Counseling provides a comprehensive, integrated approach to understanding these issues and their applications to genetic counselling.The book combines theoretical and practical approaches, including many clinical vignettes and examples of dialogue. It is written in an engaging style that conveys the emotional immediacy of genetic counselling. The emotional and social effects of genetic disorders are discussed with reference to the individual and to couple, family, and social interactions. Counselling techniques and the agenda of the genetic counselling session are then addressed in detail. Specialized aspects of prenatal diagnosis counselling, cancer risk counselling, and genetic counselling with children and adolescents are integrated with these general principles. Nondirective counselling and the psychology of risk interpretation and decision making are discussed from theoretical and historical perspectives, leading to recommendations for their application to clinical practice. The influences of ethnocultural history, beliefs and practices, for counsellee and counsellor, are then discussed as they enter into all aspects of genetic counselling.

Since the first edition of this highly acclaimed text was published in 1992, much new knowledge has been gained about the role of genetic factors in common adult disease, and we now have a better understanding of the molecular processes involved in genetic susceptibility and disease mechanisms. The Second Edition fully incorporates these advances. The entire book has been updated and twelve new chapters have been added. Most of these chapters deal with diseases such as gallstones, osteoporosis, osteoarthrits, skin cancer, other common skin diseases, prostate cancer and migraine headaches that are seen by all physicians. Others address the genetic and molecular basis of spondyloarthropathies, lupus, hemochromatosis, IgA deficiency, mental retardation, hearing loss, and the role of mitochondrial variation in adult diseases. Chapters on the evolution of human genetic disease and on animal models add important background on the complexities of these diseases. Unique clinical applications of genetics to common diseases are covered in additional new chapters on genetic counselling, pharmacogenetics, and the genetic consequences of modern therapeutics.

With the accelerating discovery of human genes, public health professionals are increasingly confronted with a large body of scientific information that will guide public health action. Because the broad mission of public health is to fulfill society's interest in assuring conditions in which people can be healthy, the integration of new genetic information in public health research, policy and program development is unavoidable. Public health leadership is urgently needed to use genetic information to improve health and prevent disease, and to address ethical, legal and social issues resulting from inappropriate use of such information. In the not too-distant future, disease prevention and health promotion programs will routinely consider whether or not to use genetic information to help target behavioral, medical or environmental intervention activities in order to maximize benefit and minimize costs and harm to individuals. In anticipation of the expected growth at the interface of genetics and public health, this book delineates a framework for the integration of advances in human genetics into public health practice. It provides a comprehensive review of public health genetics, including chapters on important general issues such as newborn and other genetic screening, the delivery of genetic services, and the ethical, legal and social implications of the use of genetics within public health. It also reviews relevant clinical topics, the historical background, cross-cultural aspects, and communication issues. Contributors come from a wide range of fields including epidemiology, biostatistics, health policy and management, health services research, behavioral and social sciences, ethics, law, health economics, and laboratory sciences.

Advances in genetics over the past 50 years have dramatically changed the understanding and management of inherited disorders, and are beginning to have a major impact on the practice of medicine overall. The rapidity of these advances means that clinicians and scientists in the field are often unfamiliar with the key research that has led to many developments that now are accepted and familiar. Few have time to search for the original papers, which are scattered and often difficult to obtain.This collection has been edited mainly for medical geneticists and genetics researchers who wish to learn more about how their field originated and developed. Brief, clearly written commentaries on each paper and section place the work in its current context and serve to unify the different parts of the book. They also help make it a readable and authoritative source of information.The papers chosen fall into several groups. First are classic descriptions of important genetic disorders, often from the pre-mendelian era. The following sections deal with the definition of human mendelian inheritance, the origins of human cytogenetics, the early development of the human gene map and the transition from biochemical genetics to human molecular genetics, the relatively recent studies that have shown how mendelian principles are increasingly modifiable, and finally advances in the treatment and management of genetic disorders, which are placed in their social context.

Recent advances in neuroscience and genetics have greatly expanded our understanding of the brain and of the etiological factors involved in developmental delay and mental retardation. At the same time, the human genome project has yielded a wealth of information on DNA sequencing, regulation of gene expression, epigenetics, and functional aspects of the genome, which newly propels investigation into the pathogenesis of mental retardation. This book makes readily available current knowledge on the subject and applies it to clinical medicine, providing information essential to neurologists, geneticists, physicians and pediatricians as they search for the causes of mental handicap in their patients. Introductory chapters cover normal and abnormal brain structure, neurogenesis, neuronal proliferation, and signal transduction. Latter chapters delve into discussions of both the environmental factors that may lead to neurocognitive deficits and the cytogenetic, biochemical and molecular defects specifically associated with mental retardation. One chapter reviews gene involvement in non-syndromic mental retardation, autism, and language deficits, as well as multifactorial and genetically complex inheritance. The text concludes with a clinically practical discussion of carrier detection, presymptomatic diagnosis, and treatment of various genetic diseases through enzyme therapy, substrate deprivation, and the use of hemapoietic stem cells.

Obesity is one of the most important contributing factors to disease throughout the world and is an area of great current interest among researchers and clinicians. The genetics of common obesity is complex, and an important thread through this labyrinth is the study of genetic syndromes in which obesity is a major component. By examining the genetic mechanisms of obesity in these syndromes, the authors will shed new light on the genetics of common obesity. This is the first book on this important and exciting new area and addreses both the molecular and clinical features of the obesity syndromes, providing hard-core information for researchers and practical guidelines for clinicians caring for obese patients.The book is divided into three sections: the first covers approaches for assessing and investigating the obese individual; the second describes nondysmorphic, monogenic forms of obesity; and the third documents key, multisystem obesity syndromes with various genetic etiologies. It is as much a reference book as it is a manual and will appeal to clinical geneticists, obesity researchers, endocrinologists, nutritionists, and medical biologists.

Molecular genetics has revolutionised our understanding of human disease and nowhere is this more apparent than the group of diseases caused by mitochondrial dysfunction. The concept of mitochondrial diseases dates back only as far as the 1960s, and they were given little credence until mutations in mitochondrial DNA were found in the late 1980s. This international edited book summarises the advances in human mitochondrial genetics made over the past decade and a half. During that time, numerous mutations of mitochondrial DNA have been discovered and more recently mitochondrial diseases have been linked to a number of nuclear gene mutations. Although individually rare, mitochondrial diseases collectively represent a common cause of genetic disease. They have myriad effects and often manifest as common disorders such as diabetes, cardiac dysfunction and neurodegenerative disease. Effective treatments are unlikely to be found for some time for the vast majority of mitochondrial disorders and so pre-natal diagnosis and genetic counselling are of primary importance in the management of mitochondrial disease.In order to make sense of the diversity of mitochondrial disease the reader is first treated to a review of mitochondrial DNA metabolism and normal mitochondrial function. The core of the book details specific mitochondrial and nuclear mutations and the diseases they cause, whilst at the same time providing further insight into mitochondrial function. Later sections assess the role of cellular and animal models in advancing our understanding of mitochondrial diseases and the prospects for novel therapeutic strategies to combat these enigmatic disorders.Mitochondrial diseases are an increasingly recognised cause of inherited disease. Most clinicians are now aware of this group of diseases and those involved in genetic counselling will recognise the need for a greater understanding of this group of disorders. This book will also appeal to scientific and medical geneticists, and to registrars who encounter this group of diseases in the clinic.

It is now almost a decade since the identification of the Huntington's Disease gene and its mutation, during which time, major advances in our understanding of this disorder have been achieved. Since publication of the first two editions of this book, there have been considerable insights into how the mutation leads to the molecular pathology, neuropathology and clinical symptoms of Huntington's Disease, and experimental tools are now in place to take this research further towards new therapeutic approaches. As a result of these major advances, this well-established series of books has required radical updating.An international group of researchers and clinicians with specialist interests in HD has been commissioned to document the recent advances in our understanding of this disease. Developments in the fields of structural biology, cell biology, neurochemistry and neuropathology, with full coverage of transgenic animal models, are discussed in detail. The clinical sections cover genetic, neurological and psychiatric aspects as well as new developments in therapy.This book will continue to provide an invaluable source of information for clinicians and scientists involved with Huntington's Disease, including geneticists, psychiatrists and neurologists, and basic science research workers in genetics and neurobiology.

Even as classic cytogenetics has given way to molecular karyotyping, and as new deletion and duplication syndromes are identified almost every day, the fundamental role of the genetics clinic remains mostly unchanged. Genetic counselors and medical geneticists explain the "unexplainable," helping families understand why abnormalities occur and whether they're likely to occur again. Chromosome Abnormalities and Genetic Counseling is the genetics professional's definitive guide to navigating both chromosome disorders and the clinical questions of the families they impact. Combining a primer on these disorders with the most current approach to their best clinical approaches, this classic text is more than just a reference; it is a guide to how to think about these disorders, even as our technical understanding of them continues to evolve. Completely updated and still infused with the warmth and voice that have made it essential reading for professionals across medical genetics, this edition of Chromosome Abnormalities and Genetic Counseling represents a leap forward in clinical understanding and communication. It is, as ever, essential reading for the field.

The third edition of Human Malformations and Related Anomalies is a comprehensive reference and clinical guide to significant human malformations.

Duchenne Muscular Dystrophy, an inherited and progressive muscle wasting disease, is one of the most common single gene disorders found in the developed world. In this fourth edition of the classic monograph on the topic, Alan Emery and Francesco Muntoni are joined by Rosaline Quinlivan, Consultant in Neuromuscular Disorders, to provide a thorough update on all aspects of the disorder.Recent understanding of the nature of the genetic defect responsible for Duchenne Muscular Dystrophy and isolation of the protein dystrophin has led to the development of new theories for the disease's pathogenesis. This new edition incorporates these advances from the field of molecular biology, and describes the resultant opportunities for screening, prenatal diagnosis, genetic counselling and from recent pioneering work with anti-sense oligonucleotides, the possibility of effective RNA therapy. Although there is still no cure for the disorder, there have been significant developments concerning the gene basis, publication of standards of care guidelines, and improvements in management leading to significantly longer survival, particularly with cardio-pulmonary care. The authors also investigate other forms of pharmacological, cellular and gene therapies.Duchenne Muscular Dystrophy will be essential reading not only for scientists and clinicians, but will also appeal to therapists and other professionals involved in the care of patients with muscular dystrophy.

This is the third edition of the foremost medical reference on hereditary hearing loss. Chapters on epidemiology, embryology, non-syndromic hearing loss, and syndromic forms of hearing loss have all been updated with particular attention to the vast amount of new information on molecular mechanisms, and chapters on clinical and molecular diagnosis and on genetic susceptibility to ototoxic factors have been added. As in previous editions, the syndromes are grouped by system (visual, metabolic, cardiologic, neurologic, musculoskeletal, endocrine, etc.), with each chapter written by a recognized expert in the field. Written for practicing clinicians, this volume is an excellent reference for physicians, audiologists, and other professionals working with individuals with hearing loss and their families, and can also serve as a text for clinical training programs and for researchers in the hearing sciences.

Texts on inborn errors of metabolism (IEMs) have traditionally focused on classical biochemistry, clinical presentation, and standard treatment approaches. Inborn Errors of Metabolism is an expansion on this model, one that establishes an innovative pathway approach and provides a new authority on this family of disease. Alongside the standard cadre of molecular and clinical underpinnings, this volume includes coverage of newborn screenings and an overarching treatment of IEMs as complex diseases -- how basic alterations can lead to complex secondary and tertiary effects in metabolism that contribute to increasingly recognized natural histories of disease.

It is written in an engaging style that conveys the emotional immediacy of genetic counselling. The emotional and social effects of genetic disorders are discussed with reference to the individual and to couple, family, and social interactions. Counselling techniques and the agenda of the genetic counselling session are then addressed in detail. Specialized aspects of prenatal diagnosis counselling, cancer risk counselling, and genetic counselling with children and adolescents are integrated with these general principles. Nondirective counselling and the psychology of risk interpretation and decision making are discussed from theoretical and historical perspectives, leading to recommendations for their application to clinical practice. The influences of ethnocultural history, beliefs and practices, for counsellee and counsellor, are then discussed as they enter into all aspects of genetic counselling.

Since the first edition of this highly acclaimed text was published in 1992, much new knowledge has been gained about the role of genetic factors in common adult disease, and we now have a better understanding of the molecular processes involved in genetic susceptibility and disease mechanisms. The Second Edition fully incorporates these advances. The entire book has been updated and twelve new chapters have been added. Most of these chapters deal with diseases such as gallstones, osteoporosis, osteoarthrits, skin cancer, other common skin diseases, prostate cancer and migraine headaches that are seen by all physicians. Others address the genetic and molecular basis of spondyloarthropathies, lupus, hemochromatosis, IgA deficiency, mental retardation, hearing loss, and the role of mitochondrial variation in adult diseases. Chapters on the evolution of human genetic disease and on animal models add important background on the complexities of these diseases. Unique clinical applications of genetics to common diseases are covered in additional new chapters on genetic counselling, pharmacogenetics, and the genetic consequences of modern therapeutics.

With the accelerating discovery of human genes, public health professionals are increasingly confronted with a large body of scientific information that will guide public health action. Because the broad mission of public health is to fulfill society's interest in assuring conditions in which people can be healthy, the integration of new genetic information in public health research, policy and program development is unavoidable. Public health leadership is urgently needed to use genetic information to improve health and prevent disease, and to address ethical, legal and social issues resulting from inappropriate use of such information. In the not too-distant future, disease prevention and health promotion programs will routinely consider whether or not to use genetic information to help target behavioral, medical or environmental intervention activities in order to maximize benefit and minimize costs and harm to individuals. In anticipation of the expected growth at the interface of genetics and public health, this book delineates a framework for the integration of advances in human genetics into public health practice. It provides a comprehensive review of public health genetics, including chapters on important general issues such as newborn and other genetic screening, the delivery of genetic services, and the ethical, legal and social implications of the use of genetics within public health. It also reviews relevant clinical topics, the historical background, cross-cultural aspects, and communication issues. Contributors come from a wide range of fields including epidemiology, biostatistics, health policy and management, health services research, behavioral and social sciences, ethics, law, health economics, and laboratory sciences.

Advances in genetics over the past 50 years have dramatically changed the understanding and management of inherited disorders, and are beginning to have a major impact on the practice of medicine overall. The rapidity of these advances means that clinicians and scientists in the field are often unfamiliar with the key research that has led to many developments that now are accepted and familiar. Few have time to search for the original papers, which are scattered and often difficult to obtain.This collection has been edited mainly for medical geneticists and genetics researchers who wish to learn more about how their field originated and developed. Brief, clearly written commentaries on each paper and section place the work in its current context and serve to unify the different parts of the book. They also help make it a readable and authoritative source of information.The papers chosen fall into several groups. First are classic descriptions of important genetic disorders, often from the pre-mendelian era. The following sections deal with the definition of human mendelian inheritance, the origins of human cytogenetics, the early development of the human gene map and the transition from biochemical genetics to human molecular genetics, the relatively recent studies that have shown how mendelian principles are increasingly modifiable, and finally advances in the treatment and management of genetic disorders, which are placed in their social context.

Recent advances in neuroscience and genetics have greatly expanded our understanding of the brain and of the etiological factors involved in developmental delay and mental retardation. At the same time, the human genome project has yielded a wealth of information on DNA sequencing, regulation of gene expression, epigenetics, and functional aspects of the genome, which newly propels investigation into the pathogenesis of mental retardation. This book makes readily available current knowledge on the subject and applies it to clinical medicine, providing information essential to neurologists, geneticists, physicians and pediatricians as they search for the causes of mental handicap in their patients. Introductory chapters cover normal and abnormal brain structure, neurogenesis, neuronal proliferation, and signal transduction. Latter chapters delve into discussions of both the environmental factors that may lead to neurocognitive deficits and the cytogenetic, biochemical and molecular defects specifically associated with mental retardation. One chapter reviews gene involvement in non-syndromic mental retardation, autism, and language deficits, as well as multifactorial and genetically complex inheritance. The text concludes with a clinically practical discussion of carrier detection, presymptomatic diagnosis, and treatment of various genetic diseases through enzyme therapy, substrate deprivation, and the use of hemapoietic stem cells.

Obesity is one of the most important contributing factors to disease throughout the world and is an area of great current interest among researchers and clinicians. The genetics of common obesity is complex, and an important thread through this labyrinth is the study of genetic syndromes in which obesity is a major component. By examining the genetic mechanisms of obesity in these syndromes, the authors will shed new light on the genetics of common obesity. This is the first book on this important and exciting new area and addreses both the molecular and clinical features of the obesity syndromes, providing hard-core information for researchers and practical guidelines for clinicians caring for obese patients.The book is divided into three sections: the first covers approaches for assessing and investigating the obese individual; the second describes nondysmorphic, monogenic forms of obesity; and the third documents key, multisystem obesity syndromes with various genetic etiologies. It is as much a reference book as it is a manual and will appeal to clinical geneticists, obesity researchers, endocrinologists, nutritionists, and medical biologists.

Molecular genetics has revolutionised our understanding of human disease and nowhere is this more apparent than the group of diseases caused by mitochondrial dysfunction. The concept of mitochondrial diseases dates back only as far as the 1960s, and they were given little credence until mutations in mitochondrial DNA were found in the late 1980s. This international edited book summarises the advances in human mitochondrial genetics made over the past decade and a half. During that time, numerous mutations of mitochondrial DNA have been discovered and more recently mitochondrial diseases have been linked to a number of nuclear gene mutations. Although individually rare, mitochondrial diseases collectively represent a common cause of genetic disease. They have myriad effects and often manifest as common disorders such as diabetes, cardiac dysfunction and neurodegenerative disease. Effective treatments are unlikely to be found for some time for the vast majority of mitochondrial disorders and so pre-natal diagnosis and genetic counselling are of primary importance in the management of mitochondrial disease.In order to make sense of the diversity of mitochondrial disease the reader is first treated to a review of mitochondrial DNA metabolism and normal mitochondrial function. The core of the book details specific mitochondrial and nuclear mutations and the diseases they cause, whilst at the same time providing further insight into mitochondrial function. Later sections assess the role of cellular and animal models in advancing our understanding of mitochondrial diseases and the prospects for novel therapeutic strategies to combat these enigmatic disorders.Mitochondrial diseases are an increasingly recognised cause of inherited disease. Most clinicians are now aware of this group of diseases and those involved in genetic counselling will recognise the need for a greater understanding of this group of disorders. This book will also appeal to scientific and medical geneticists, and to registrars who encounter this group of diseases in the clinic.

It is now almost a decade since the identification of the Huntington's Disease gene and its mutation, during which time, major advances in our understanding of this disorder have been achieved. Since publication of the first two editions of this book, there have been considerable insights into how the mutation leads to the molecular pathology, neuropathology and clinical symptoms of Huntington's Disease, and experimental tools are now in place to take this research further towards new therapeutic approaches. As a result of these major advances, this well-established series of books has required radical updating.An international group of researchers and clinicians with specialist interests in HD has been commissioned to document the recent advances in our understanding of this disease. Developments in the fields of structural biology, cell biology, neurochemistry and neuropathology, with full coverage of transgenic animal models, are discussed in detail. The clinical sections cover genetic, neurological and psychiatric aspects as well as new developments in therapy.This book will continue to provide an invaluable source of information for clinicians and scientists involved with Huntington's Disease, including geneticists, psychiatrists and neurologists, and basic science research workers in genetics and neurobiology.

Even as classic cytogenetics has given way to molecular karyotyping, and as new deletion and duplication syndromes are identified almost every day, the fundamental role of the genetics clinic remains mostly unchanged. Genetic counselors and medical geneticists explain the "unexplainable," helping families understand why abnormalities occur and whether they're likely to occur again. Chromosome Abnormalities and Genetic Counseling is the genetics professional's definitive guide to navigating both chromosome disorders and the clinical questions of the families they impact. Combining a primer on these disorders with the most current approach to their best clinical approaches, this classic text is more than just a reference; it is a guide to how to think about these disorders, even as our technical understanding of them continues to evolve. Completely updated and still infused with the warmth and voice that have made it essential reading for professionals across medical genetics, this edition of Chromosome Abnormalities and Genetic Counseling represents a leap forward in clinical understanding and communication. It is, as ever, essential reading for the field.

Duchenne Muscular Dystrophy, an inherited and progressive muscle wasting disease, is one of the most common single gene disorders found in the developed world. In this fourth edition of the classic monograph on the topic, Alan Emery and Francesco Muntoni are joined by Rosaline Quinlivan, Consultant in Neuromuscular Disorders, to provide a thorough update on all aspects of the disorder.Recent understanding of the nature of the genetic defect responsible for Duchenne Muscular Dystrophy and isolation of the protein dystrophin has led to the development of new theories for the disease's pathogenesis. This new edition incorporates these advances from the field of molecular biology, and describes the resultant opportunities for screening, prenatal diagnosis, genetic counselling and from recent pioneering work with anti-sense oligonucleotides, the possibility of effective RNA therapy. Although there is still no cure for the disorder, there have been significant developments concerning the gene basis, publication of standards of care guidelines, and improvements in management leading to significantly longer survival, particularly with cardio-pulmonary care. The authors also investigate other forms of pharmacological, cellular and gene therapies.Duchenne Muscular Dystrophy will be essential reading not only for scientists and clinicians, but will also appeal to therapists and other professionals involved in the care of patients with muscular dystrophy.

This is the third edition of the foremost medical reference on hereditary hearing loss. Chapters on epidemiology, embryology, non-syndromic hearing loss, and syndromic forms of hearing loss have all been updated with particular attention to the vast amount of new information on molecular mechanisms, and chapters on clinical and molecular diagnosis and on genetic susceptibility to ototoxic factors have been added.
