Map of Finland showing birthplaces of grandparents (red) and parents (blue) of 34 patients with CLD. The distributions are very similar, showing that recent moves from the eastern and north-central parts of the country to the south and west that would significantly distort the distribution have not occurred. Birthplaces are almost entirely confined to new Finland that is, regions populated after the 1500s. (Adapted from ref. 28.)
