In the past decade, large scale genotyping has led to discoveries of numerous sequence variants that confer increased risk of many common complex diseases. Interestingly, a substantial proportion of pioneering genetic work has originated from the small nation of Iceland and has been facilitated by an extensive genealogy database. We provide examples of relevant observations made so far in several major disease categories central to internal medicine practice. Some of these findings offer new mechanistic clues into the pathophysiology of common disorders and may suggest novel approaches in diagnosis and drug therapy.
