Ethical issues in neurogenetic disorders

Ethical issues in the evaluation of adults with suspected genetic neuromuscular disorders

Genetic testing is rapidly becoming an increasingly significant part of the diagnostic armamentarium of neuromuscular clinicians. Although technically easy to order, the results of such testing, whether positive or negative, have potentially enormous consequences for the individual tested and for family members. As a result, ethical considerations must be in the forefront of the physician's agenda when obtaining genetic testing. Informed consent is an important starting point for discussions between physicians and patients, but the counseling embedded in the informed consent process must be an ongoing part of subsequent interactions, including return of results and follow-up. Patient autonomy, including the right to know and right not-to-know results, must be respected. Considerations of capacity, physician beneficence and nonmaleficence, and privacy all play roles in the process. Muscle Nerve 54: 997-1006, 2016.

Neurogenetics in Peru: clinical, scientific and ethical perspectives

Neurogenetics, the science that studies the genetic basis of the development and function of the nervous system, is a discipline of recent development in Peru, an emerging Latin American country. Herein, we review the clinical, scientific and ethical aspects regarding the development of this discipline, starting with the first molecular diagnosis of neurogenetic diseases, to family and population-based genetic association studies. Neurogenetics in Peru aims to better explain the epidemiology of monogenic and complex neurodegenerative disorders that will help in implementing public health policies for these disorders. The characterization of Peru and its health system, legal issues regarding rare diseases and the historical milestones in neurogenetics are also discussed.

Genetic testing in the epilepsies-developments and dilemmas

In the past two decades, the number of genes recognized to have a role in the epilepsies has dramatically increased. The availability of testing for epilepsy-related genes is potentially helpful for clarification of the diagnosis and prognosis, selection of optimal treatments, and provision of information for family planning. For some patients, identification of a specific genetic cause of their epilepsy has important personal value, even in the absence of clear clinical utility. The availability of genetic testing also raises new issues that have only begun to be considered. These issues include the growing importance of educating physicians about when and how to test patients, the need to ensure that affected individuals and their families can make informed choices about testing and receive support after receiving the results, and the question of what the positive and negative consequences of genetic testing will be for affected individuals, their family members, and society.
