Available in PDF, EPUB and Kindle. Book excerpt: Medical Genetics: What is MOSAICISM? When the fertilized egg begins to divide, it replicates its genetic material in cellular offspring. This cell replication builds and builds, creating tissues and organs in the body. In theory, each replicated cell should contain the exact same genetic information as the fertilized egg. However, this is not always the case. In rare instances, new genetic changes can occur in these replicated cells. These changes occur on the chromosomes, which are carry all of a person’s genetic information, located in each cell’s nucleus. Until recently, scientists thought the condition was straightforward—either a person had mosaicism or not. As genetic sequencing technology becomes more sophisticated, a picture is emerging in the field of genetics showing that we all have some amount of mosaicism. The more frequently mosaicism is found in the body, the greater likelihood a person can develop a health condition because of it. Thus, it is endeavoured in this E-Booklet to precisely discuss the followings: · How does Mosaicism occur? · Types of Mosaicism · Types of Disorders caused by Mosaicism along with ILLUSTRATIONS. · How is Mosaicism Diagnosed? · Use in Experimental Biology · Prognosis · Can Mosaicism be Prevented? …Dr. H.

Download or read book Genetic Mosaicism written by János Szabad and published by Cambridge Scholars Publishing. This book was released on 2021-06-17 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: The presence of green and yellow ornamental plants around us, dark spots on our skin, people with brown and blue mosaic irises, and white-spotted dogs and horses are all well-known phenomena of life, and are recognisable genetic mosaics. Although such genetics mosaics live with us (and, in fact, we are all a genetic mosaics), little is known about the genetic bases of their origin. This book provides a general overview of the mechanisms that lead to the formation of different types of mosaics, listing an ample collection of examples to illustrate the impact of the genetic mosaics on our life. The book will appeal to the reader interested in understanding the relationship between genetic events and mosaicism, especially undergraduate and graduate students and medical doctors, as well as experts engaged in horticulture and animal breeding.
Download or read book Mosaicism in Human Skin written by Rudolf Happle and published by Springer Nature. This book was released on 2022-11-24 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: This second edition offers a fully revised and updated work on a rapidly growing field of knowledge, and was prepared by two experts whose goal was to explain the molecular basis of mosaic skin disorders in a language that is accessible for practicing physicians and medical students alike. It presents a timely and comprehensive overview of the strikingly manifold patterns and peculiarities of mosaic skin disorders in a straightforward, reader-friendly way that will help physicians to further improve genetic counseling and treatment outcomes. The first two parts of the book are devoted to the mechanisms and patterns of cutaneous mosaicism, and include an explanation of genomic and epigenetic mosaicism and a description of the archetypical segmental patterns including the lines of Blaschko and the flag-like, phylloid and lateralization pattern, the non-segmental pattern of large congenital melanocytic nevi, and the sash-like arrangement as noted in a particular type of cutis tricolor. The concept of lethal mutations surviving as mosaics has now been confirmed by molecular analysis in many sporadically occurring phenotypes. The difference between monoallelic and biallelic traits has deepened our understanding of hereditary mosaics, especially of multiple benign skin tumors. Moreover, recognition of the fundamental difference between the simple segmental and the superimposed types of mosaicism is important for the purpose of genetic counseling. In the third part, the various mosaic skin disorders are examined in depth, including nevi, didymotic disorders, other binary genodermatoses, mosaic manifestations of autosomal skin disorders, and nevoid skin disorders such as phenotypes reflecting functional X-chromosome mosaicism or a superimposed mosaic manifestation of common skin diseases with a polygenic background. Reader-friendly and clearly structured, Mosaicism in Human Skin will appeal to both experienced dermatologists and residents in training, as well as to medical geneticists and pediatricians.
Download or read book Females Are Mosaics written by Barbara Migeon and published by Oxford University Press. This book was released on 2007-03-15 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Women can be described as genetic mosaics because they have two distinctly different types of cells throughout their bodies. Unlike males, who have one X chromosome (inherited from their mother), females have two X chromosomes in every cell (one from each parent). The fathers copy works in some cells, while the mothers copy works in others. These two X chromosomes often function differently, especially if one carries a defective gene. Much has been written about the Y chromosome and its role in inducing maleness. This will be the first book about the X chromosome as a key to female development and the role of X-related factors in the etiology of sex differences in human disease. Barbara Migeon, from the renowned McKusick-Nathan Institute at Johns Hopkins, is a major figure in clinical genetics and is eminently qualified to write this book, and she writes clearly and effectively. She describes both the underlying molecular mechanisms and the remarkable genetic consequences of X inactivation and its role in determining the biological concepts characteristic of women. Females are Mosaics will be valuable to geneticists, biologists, and all health professionals interested in women's health.

Available in PDF, EPUB and Kindle. Book excerpt: Mosaicism is a powerful biologic concept, originally developed from studying plants and animals. All cutaneous neoplasms, both benign and malignant, reflect mosaicism, which is the necessary basis to explain numerous human skin disorders. For example, various mosaic patterns visualize the embryonic development of human skin and X-linked skin disorders explain why women live longer than men, and so on. This book presents, for the first time, a comprehensive overview on the strikingly manifold patterns and peculiarities of mosaic skin disorders. This reader-friendly structured and straightforward publication will help the dermatologist to understand the underlying molecular mechanisms of skin disorders in order to further improve the treatment outcome.

Download or read book Heritable Human Genome Editing written by The Royal Society and published by National Academies Press. This book was released on 2021-01-16 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: Heritable human genome editing - making changes to the genetic material of eggs, sperm, or any cells that lead to their development, including the cells of early embryos, and establishing a pregnancy - raises not only scientific and medical considerations but also a host of ethical, moral, and societal issues. Human embryos whose genomes have been edited should not be used to create a pregnancy until it is established that precise genomic changes can be made reliably and without introducing undesired changes - criteria that have not yet been met, says Heritable Human Genome Editing. From an international commission of the U.S. National Academy of Medicine, U.S. National Academy of Sciences, and the U.K.'s Royal Society, the report considers potential benefits, harms, and uncertainties associated with genome editing technologies and defines a translational pathway from rigorous preclinical research to initial clinical uses, should a country decide to permit such uses. The report specifies stringent preclinical and clinical requirements for establishing safety and efficacy, and for undertaking long-term monitoring of outcomes. Extensive national and international dialogue is needed before any country decides whether to permit clinical use of this technology, according to the report, which identifies essential elements of national and international scientific governance and oversight.
Download or read book Small Supernumerary Marker Chromosomes sSMC written by Thomas Liehr and published by Springer Science & Business Media. This book was released on 2011-11-03 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human beings normally have a total of 46 chromosomes, with each chromosome present twice, apart from the X and Y chromosomes in males. Some three million people worldwide, however, have 47 chromosomes: they have a small supernumerary marker chromosome (sSMC) in addition to the 46 normal ones. This sSMC can originate from any one of the 24 human chromosomes and can have different shapes. Approximately one third of sSMC carriers show clinical symptoms, while the remaining two thirds manifest no phenotypic effects. This guide represents the first book ever published on this topic. It presents the latest research results on sSMC and current knowledge about the genotype-phenotype correlation. The focus is on genetic diagnostics as well as on prenatal and fertility-related genetic counseling. A unique feature is that research meets practice: numerous patient reports complement the clinical aspects and depict the experiences of families living with a family member with an sSMC.
