To me it seems reasonable that many diseases are more or less common based on race. But our concept and specially NA concept is not nearly fine-grained enough for it to work in many cases. Looking at Europe it seems there are differences even inside countries and groups that now are considered single ethnicity. So what would be needed is to track back to that level of history of population.
