This wide ranging and compelling account surveys the exciting opportunities and difficult problems which arise from the new human genetics. The availability of increasingly sophisticated information on our genetic make-up presents individuals, and society as a whole, with difficult decisions. Although it is hoped that these advances will ultimately lead the way to the effective treatment and screening for all diseases with a genetic component, at present many individuals are ‘condemned’ to a life sentence, in the knowledge that they, or their children, will suffer from an incurable genetic disease. This is the first book to attempt to explore and survey these issues from such a variety of perspectives: from personal accounts of individuals coping with the threat of genetic disease, from the viewpoint of clinicians and scientists, and from those concerned with psychosocial, legal and ethical aspects.
