Remember when genetic testing was good material for science fiction movies? Sounded outrageous then…but now it’s a reality.
Welcome to the future!
Gene mapping allows millions of people to research their ancestry. (Sometimes the results are surprising.) Learning about your origins is interesting and fun, but more important, genetic testing advances our understanding of different medical issues. Companies like 23andMe find markers that determine if we’re prone to certain diseases or conditions.
For example, suppose some of your family members lose their eyesight as they age. Yet others have 20/20 vision as long as they live. Chances are, those with sight problems are pre-disposed to Age-related Macular Degeneration. Testing your saliva can determine if you’re included in that group. Currently there is no cure. However, the information alerts you to preventative measures to take so that you reduce and possibly eliminate being affected.
It’s important to understand that this type of testing is not perfect. Results need to be evaluated with your doctor to determine what, if anything, you should or should not do.
