Geneticists have been studying the population of Newfoundland for decades. The gene pool is limited, because of our small population and historically isolated communities. That means it's easier for scientists to identify genes that cause hereditary diseases, and to work on treatments for them. Now researchers are taking that work into the future...by looking at the past. Ed Gilbert is a lecturer at the Royal College of Surgeons in Ireland.
