Genomics 101
Genetic knowledge has achieved an important new level of clarity and detail. We now can scan genetic instructions written in your chromosomes and spot places where you've inherited disease-prone versions. For the first time, we have the opportunity to see where your personal genetic code has raised your odds of having a common condition such as diabetes — or boosted your chances of a rare condition like Crohn's disease. Our knowledge of how the genome misbehaves to predispose you to disease is constantly increasing and becoming more accurate as the science evolves. Today's genomics — the study of your entire genetic code — is far different from the genetics you might remember from school.
With this knowledge comes power. You can take appropriate action: setting your health priorities, taking prevention measures, becoming vigilant about early symptoms, or beginning treatment earlier, which can improve health outcomes.
