Book Description
Benign & Pathological Chromosomal Imbalances systematically clarifies the disease implications of cytogenetically visible copy number variants (CG-CNV) using cytogenetic assessment of heterochromatic or euchromatic DNA variants. While variants of several megabasepair can be present in the human genome without clinical consequence, visually distinguishing these benign areas from disease implications does not always occur to practitioners accustomed to costly molecular profiling methods such as FISH, aCGH, and NGS. As technology-driven approaches like FISH and aCGH have yet to achieve the promise of universal coverage or cost efficacy to sample investigated, deep chromosome analysis and molecular cytogenetics remains relevant for technology translation, study design, and therapeutic assessment. Knowledge of the rare but recurrent rearrangements unfamiliar to practitioners saves time and money for molecular cytogeneticists and genetics counselors, helping to distinguish benign from harmful CG-CNV. It also supports them in deciding which molecular cytogenetics tools to deploy. Shows how to define the inheritance and formation of cytogenetically visible copy number variations using cytogenetic and molecular approaches for genetic diagnostics, patient counseling, and treatment plan development Uniquely classifies all known variants by chromosomal origin, saving time and money for researchers in reviewing benign and pathologic variants before costly molecular methods are used to investigate Side-by-side comparison of copy number variants with their recently identified submicroscopic form, aiding technology assessment using aCGH and other techniques

Book Description
Explore the past, present, and future of cancer cytogenetics In Abnormal Chromosomes: The Past, Present, and Future of Cancer Cytogenetics, globally renowned researchers Drs. Sverre Heim and Felix Mitelman deliver a state-of-the-art review of how cancer cytogenetic analyses have contributed to an improved understanding of tumorigenesis as well as to the diagnosis and treatment of cancer patients. The book also discusses how cytogenetics – the study of chromosomes - meets, interacts with, and cross-fertilizes other investigative technologies, including molecular somatic cell genetics. The book provides an impetus to think more deeply about the role chromosomes, and their abnormalities, play in health and disease, especially in neoplastic disorders. From which origins did cytogenetics develop? How did the finding of acquired chromosomal abnormalities in cells of leukemias and solid tumors influence our understanding of cancer as a biological process? How was information of this nature put to good use in the clinical management of cancer patients? Abnormal Chromosomes: The Past, Present, and Future of Cancer Cytogenetics offers readers: A thorough introduction to ancient theories of disease, the advent of cellular pathology, and how a scientific interest in chromosomes developed Comprehensive exploration of the conceptual importance of Theodor Boveri and his somatic mutation theory of cancer A detailed chronological resume of cancer cytogenetic discoveries during the 20th century In-depth discussions of the role of chromosome abnormalities, oncogenes, and tumor suppressor genes in leukemias, lymphomas, and solid tumors, together with a survey of what chromosome analyses have revealed about the clonal evolution of neoplastic cell populations A discussion of the importance of pathogenetic classifications of neoplastic diseases, the role chromosome abnormalities play in this context, and which technological breakthroughs can be expected in chromosome-oriented cancer research Abnormal Chromosomes: The Past, Present, and Future of Cancer Cytogenetics was written for everyone with a scientific or clinical interest in cancer, especially how acquired chromosome abnormalities lead to neoplastic transformation. The book teaches how cytogenetic analyses contribute to a better understanding of tumorigenesis, but also how the finding of specific chromosome aberrations can be crucial for the diagnosis, prognosis, and management of cancer patients.

Book Description
This second edition focuses on the study of human interphase chromosomes and its relation to health and disease. Orchestrated organization and behavior of the human genome in interphase nuclei at chromosomal level has been repeatedly shown to play a significant role in almost all basic biological processes involved in the processing and inheritance of genetic information within and between species. Accordingly, post-genomic bioscience appeals to basic and applied studies of interphase nuclei genetics and genomics with special attention to interphase chromosome behavior in health and disease. Additionally, elucidating the role of interphase chromosome behavior during development, chromosome/DNA replication, DNA reparation opens new horizons for basic and applied bioscience Studies of interphase nuclei have an appreciable impact on different areas of biomedical sciences such as cell biology, neurobiology, cancer research, developmental biology, epigenetics, cytogenetics, and medical genetics, as a whole. Moreover, development of innovative and emergent technologies to analyze interphase nuclei are closely associated with application of these techniques in diagnostic and research practices to solve reproductive problems (including infertility and spontaneous abortions), to investigate congenital malformations (including those produced by aneuploidy and other chromosome abnormalities); genetic diseases (including cardiac, immune, neurological and psychiatric diseases), and cancer. This second edition serves as a source of updated valuable information and promising ideas for a wide audience of professionals in biomedicine including researchers, scientists, and healthcare professionals in human genetics, cytogenetics, and developmental biology.

Book Description
Supernumerary B chromosomes (Bs) are dispensable genetic elements found in thousands of species of plants and animals, and some fungi. Since their discovery more than a century ago, they have been a source of puzzlement, as they only occur in some members of a population and are absent from others. When they do occur, they are often harmful, and in the absence of “selfishness”, based on mechanisms of mitotic and meiotic drive, there appears to be no obvious reason for their existence. Cytogeneticists have long wrestled with questions about the biological existence of these enigmatic elements, including their lack of any adaptive properties, apparent absence of functional genes, their origin, sequence organization, and co-evolution as nuclear parasites. Emerging new technologies are now enabling researchers to step up a gear, to look enthusiastically beyond the previous limits of the horizon, and to uncover the secrets of these “silent” chromosomes. This book provides a comprehensive guide to theoretical advancements in the field of B chromosome research in both animal and plant systems.

Book Description
This book focus on genetic diagnostics for Uniparental Disomy (UPD), a chromosomal disorder defined by the exceptional presence of a chromosome pair derived from only one parent, which leads to a group of rare diseases in humans. First the molecular and cytogenetic background of UPD is described in detail; subsequently, all available information of the various chromosomal origins and the latest findings on genotype-phenotype correlations and clinical consequences are discussed. Numerous personal reports from families with a child suffering from a UPD-induced syndrome serve to complement the scientific and clinical aspects. Their experiences with genetic counseling and living with a family member affected by this chromosomal aberration present a vivid picture of what UPD means for its victims.

Book Description
Cytogenomics demonstrates that chromosomes are crucial in understanding the human genome and that new high-throughput approaches are central to advancing cytogenetics in the 21st century. After an introduction to (molecular) cytogenetics, being the basic of all cytogenomic research, this book highlights the strengths and newfound advantages of cytogenomic research methods and technologies, enabling researchers to jump-start their own projects and more effectively gather and interpret chromosomal data. Methods discussed include banding and molecular cytogenetics, molecular combing, molecular karyotyping, next-generation sequencing, epigenetic study approaches, optical mapping/karyomapping, and CRISPR-cas9 applications for cytogenomics. The book’s second half demonstrates recent applications of cytogenomic techniques, such as characterizing 3D chromosome structure across different tissue types and insights into multilayer organization of chromosomes, role of repetitive elements and noncoding RNAs in human genome, studies in topologically associated domains, interchromosomal interactions, and chromoanagenesis. This book is an important reference source for researchers, students, basic and translational scientists, and clinicians in the areas of human genetics, genomics, reproductive medicine, gynecology, obstetrics, internal medicine, oncology, bioinformatics, medical genetics, and prenatal testing, as well as genetic counselors, clinical laboratory geneticists, bioethicists, and fertility specialists. Offers applied approaches empowering a new generation of cytogenomic research using a balanced combination of classical and advanced technologies Provides a framework for interpreting chromosome structure and how this affects the functioning of the genome in health and disease Features chapter contributions from international leaders in the field
