According to the Human Genome Project, as well as numerous medical research groups, significant new findings on genetic disorders occur nearly every week. Information on many of these disorders, however, is extremely difficult to come by -- until now. The Gale Encyclopedia Of Genetic Disorders addresses the need for current, hard-to-find facts on these emerging discoveries. The 3-vol. Encyclopedia provides clear, complete information on genetic disorders, including conditions, tests, procedures, treatments and therapies, in articles that are both comprehensive and easy to understand in language accessible to laypersons. Students will want to consult the Gale Encyclopedia of Genetic Disorders for useful information on a range of well-known disorders, including Down Syndrome, Trisomy, Hemophilia and Tourette Syndrome, and rarely seen diseases such as Meckel Syndrome, Neuraminidase Deficiency and Phenylketonuria. Presented in a single alphabetical sequence, entries range in length from 1,500 to 5,000 words. Entries relating to genetic disorders are presented in articles arranged in a standardized format for quick comparison and ease of use, while nondisorder topics are covered in detail with extended entries. Articles contain some or all of the following sections: definition, description -- overview of the disorder, genetic profile, demographics, signs and symptoms, diagnosis -- normal and abnormal test results are described, treatment and management, prognosis, key terms, resources -- bibliographies or contact information are provided.
