Raising hopes for disease treatment and prevention, but also the specter of discrimination and "designer genes," genetic testing is potentially one of the most socially explosive developments of our time. This book presents a current assessment of this rapidly evolving field, offering principles for actions and research and recommendations on key issues in genetic testing and screening. Advantages of early genetic knowledge are balanced with issues associated with such knowledge: availability of treatment, privacy and discrimination, personal decision-making, public health objectives, cost, and more. Among the important issues covered: Quality control in genetic testing. Appropriate roles for public agencies, private health practitioners, and laboratories. Value-neutral education and counseling for persons considering testing. Use of test results in insurance, employment, and other settings.

This book addresses the biological, moral and legal issues which arising prenatal testing of late onset neurogenetic disease. The contributors focus specifically on Huntington's Disease, which is used as a model for other late onset neurogenetic diseases. The ethical and legal aspects of prenatal testing and preimplantation genetic diagnosis are discussed with reference to case histories. This volume will provide valuable insights for all those involved in dealing with these challenging issues.

Of major issues identified for consideration both before genetic testing for late onset disorders is offered and during the provision of such tests. These relate principally to requests for genetic testing from healthy relatives of patients with a late onset genetic disorder. Population-based genetic screening, diagnostic testing of sympomatic individuals and genetic susceptibility testing for common disorders are also briefly considered.

Gene tests (also called DNA-based tests), the newest and most sophisticated of the techniques used to test for genetic disorders, involve direct examination of the DNA molecule itself. Other genetic tests include biochemical tests for such gene products as enzymes and other proteins and for microscopic examination of stained or fluorescent chromosomes. Genetic tests are used for several reasons, including: Carrier screening, which involves identifying unaffected individuals who carry one copy of a gene for a disease that requires two copies for the disease to be expressed; Preimplantation genetic diagnosis prenatal diagnostic testing new-born screening; Presymptomatic testing for predicting adult-onset disorders such as Huntington's disease; Presymptomatic testing for estimating the risk of developing adult-onset cancers and Alzheimer's disease; and Confirmational diagnosis of a symptomatic individual forensic/identity testing. In gene tests, scientists scan a patient's DNA sample for mutated sequences. A DNA sample can be obtained from any tissue, including blood. probes, whose sequences are complementary to the mutated sequences. These probes will seek their complement among the three billion base pairs of an individual's genome. If the mutated sequence is present in the patient's genome, the probe will bind to it and flag the mutation. Another type of DNA testing involves comparing the sequence of DNA bases in a patient's gene to a normal version of the gene. This book gathers important research in this field.
