How much do genes determine health? should we all check genomes?

It's variable: For any given disease, there is a contribution of genetics, environment, diet and development. For rare genetic syndromes like pku, the genetic component is 100% while in type ii diabetes, genetics is about 45%. I do not recommend whole genome screening as that is often too much information to make rational decisions. I would suggest genetic susceptibility testing for specific conditions.
