I believe that genetic predisposition is the number two determinant of health, after lifestyle. Just touching on the long QT example, recent studies have indicated that the incidence of long QT syndrome is 20 times higher in certain first nations communities in northern British Columbia, and the specific genetic markers for long QT are linked to type 2 diabetes, which is, of course, a major health concern in first nation communities.
When we're talking about this, it could have significant public health benefits across Canada.
