Genetics and medicalisation Genetics could drive a new wave of medicalisation if genetic tests are accepted without appropriate clinical evaluation

摘要

In the public imagination genetic science has already brought us close to a world in which tests and cures are available for most diseases. The immediate prospects are, however, decidedly more prosaic. With the exception of the relatively rare high penetrance, single gene disorders, genetic tests differ little from most other medical tests, providing evidence of statistical risk only. Inflated perceptions of the value of specific genetic tests could drive a wave of inappropriate medicalisation. Genetic claims, tests, and treatments, like others, should be subjected to evaluation to establish their clinical usefulness, so that doctors and patients can act on sound evidence.
