Having seen this in earlier posts, I have wondered if there really is a greater incidence in Europe due to the genetic link of Europeans? Just because it is 1:200 in Europe should we then expect that all Asians should also be 1:200? All Eskimos? All Africans? I have no doubt there is some underdiagnosis in U.S. (and elsewhere) -- but is it really that bad? I don't think U.S. doctors are really any worse than in other parts of the world. In fact, I would hope they have more informaton than most.
