Synopsis:
Genes provide the information that directs the human body's basic cellular activities. Research on the human genome has shown that the DNA sequences of any two individuals are 99.9 percent identical. That 0.1 percent variation, however, is profoundly important. It contributes to visible differences, like height and hair color, and also to invisible differences, such as increased risk for-or protection from-a myriad of diseases and disorders. As medical researchers unlock the secrets of the human genome, they are learning that nearly all diseases have a genetic component. Some are caused by a mutation in a gene or group of genes. Such mutations can occur randomly or as the result of exposure to hazardous conditions or substances. Other disorders are hereditary. These can be passed down from generation to generation within a family. Finally, many-perhaps most-genetic disorders are caused by a combination of small variations in genes operating in concert with environmental factors. Genetic Disorders Sourcebook, Seventh Edition offers updated information on how genes work and how genetic mutations affect health. It provides facts about the most common genetic disorders, including those that arise from mutations in specific genes-for example, muscular dystrophy, sickle cell anemia, and cystic fibrosis-as well as those arising from chromosomal abnormalities- such as Down syndrome and fragile X syndrome. A section on disorders with genetic and environmental components explains the hereditary components of Alzheimer disease, cancer, diabetes, mental illness, obesity, addiction, and others. Reports on current research initiatives provide detailed information on the newest breakthroughs in the causes and treatments of genetic disorders, including strategies, like gene therapy, nutrigenomics, and pharmacogenetics that could radically change how we treat these disorders in the future. A section for parents of children with genetic disorders offers
