Annotated Bibliography of Medical Literature about the Volga Germans

There has been considerable medical research conducted using Volga Germans and their descendants as the subjects. Because the gene pool of this group is often smaller than that of the general public, there are fewer external factors that must be accounted for when drawing conclusions. This bibliography captures some of this research.
