The founders of Sottunga are identified, and the genetic contributions of each founder to descending birth cohorts are estimated. Founders born before 1700 have far more descendants in the contemporary gene pool than do more recent founders. However, because of migration and depopulation since 1900, the expected genetic contributions of the early founders to the present\u2010day population are similar to those of later founders.<\/jats:p>\n                  <jats:p>A descendant in the contemporary population has a 2% chance of having inherited a particular gene from the founder who makes the largest single contribution to the gene pool. This corresponds approximately to a 2% probability of inheriting an autosomal dominant disease gene from this founder. Given an average inbreeding coefficient of 0.0016, the probability of inheriting two recessive disease genes from this founder is 0.000032. The incidence of autosomal dominant von Willebrand disease in Sottunga is greater than 10% while that of autosomal recessive tapetoretinal disease is 1.5%. We conclude, therefore, that the high frequencies of these diseases are not due to the disproportionate genetic contribution of one or a few particular founders. It is more likely that these disease genes occurred in high frequency in the initial population or were introduced repeatedly through time.<\/jats:p>","DOI":"10.1002\/ajpa.1330770306","type":"journal-article","created":{"date-parts":[[2006,2,4]],"date-time":"2006-02-04T04:50:40Z","timestamp":1139028640000},"page":"335-346","source":"Crossref","is-referenced-by-count":28,"title":["Founder effect and genetic disease in Sottunga, Finland"],"prefix":"10.1002","volume":"77","author":[{"given":"Elizabeth","family":"O'Brien","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"L.
