Some scandanavian countries have complete health records on all their citizens and some are working on national DNA banks. Some of these will be made available for research after some form of anonymization.
For values of "some" which are in the set of all nation-states known as "Iceland". There is a lot of controversy about it over there (see various news reports in Scientific American, Nature, New Scientist et.c over the past couple of years). AFAIK it is going ahead. The point about Iceland is that almost all the population is descended from a comparatively small number of Norse (& even fewer Irish) colonists in historical times & they keep good births-marriages-and-deaths records. So their traditional genetics is well-known & some quite deep family histories are retrievable. So the DNA data can maybe be matched with that to produce lots of interesting test cases about hereditary diseases. Ken Brown
