Is it appropriate to undergo a comprehensive DNA test despite the possibility of finding out that you may have a severe disease-causing mutation?
Considering how attitudes can influence health, is it wise to undergo a comprehensive DNA test despite the possibility of discovering a defection in the process?
Attitudes indeed influence health; a happy disposition at least maintains a good health. The dangerous point of knowledge is that by knowing something it can become a self-fulfilling prophecy. You become what you think. If you discover you have such a disease causing mutation, you may think you are doomed -- and chronically focusing on that thought will doom you. However, knowing that you have a disease causing mutation might also force you to change lifestyle habits that mitigate the genetic effect, in which case the knowledge led to an improved health. It's all how you process and apply the information. Deciding to get that information is a personal choice, and its appropriateness can only be determined by the person deciding to undergo the test or not.
