Predictive medicine

Introduction

This unit is an adapted extract from the Open University course Learn about human genetics and health issues which you can study just for interest [Tip: hold Ctrl and click a link to open it in a new tab. (Hide tip)] , or study for credit.

In this unit you will learn how advances in genetics could change the way in which diseases are diagnosed and managed. The advent of predictive medicine, based on more detailed DNA profiling of individual genotypes using technologies like gene chips, rather than screening for one gene at a time, may shift the relationship between doctor and patient. People will be seeking advice on how to manage their susceptibilities or genetic risks, rather than looking for treatment for an already existing disorder.
