title: [Genetic prediction in medicine].
abstract: Presymptomatic or predictive genetic testing concerns healthy people. Its aim is to determine individuals at risk for a disease. Presymptomatic testing concerns mainly Mendelian diseases; an abnormal test result will lead to development of the disease in most cases in later life. Predictive testing concerns multifactorial or low penetrating Mendelian diseases; the test result will modify the risk of disorder occurring but with a much smaller degree of certainty.
