"... The authors noted that in 2011 there were an estimated 225,500 new cases of ovarian cancer worldwide. Although some women are at greatly elevated risks of ovarian cancer due to inherited mutations in the BRCA1 and BRCA2 genes (and Lynch Syndrome amongst other rarer syndomes), these are rare in the population and account for perhaps 10 percent of cases. However, a substantial portion of genetic influence on ovarian cancer risk has been “unexplained” and some of that may be due to common genetic variants. Sellers points out that “the Il1A variant that was most strongly protective is carried by 30 percent of women in the study, so the impact at the population level is not trivial.”
