Epithelial ovarian cancer has a major heritable component, but the known susceptibility genes explain less than half the excess familial risk. We performed a genome-wide association study (GWAS) to identify common ovarian cancer susceptibility alleles. We evaluated 507,094 SNPs genotyped in 1,817 cases and 2,353 controls from the UK and approximately 2 million imputed SNPs. We genotyped the 22,790 top ranked SNPs in 4,274 cases and 4,809 controls of European ancestry from Europe, USA and Australia. We identified 12 SNPs at 9p22 associated with disease risk (P < 10(-8)).="" the="" most="" significant="" snp="" (rs3814113;="" p="2.5" x="" 10(-17))="" was="" genotyped="" in="" a="" further="" 2,670="" ovarian="" cancer="" cases="" and="" 4,668="" controls,="" confirming="" its="" association="" (combined="" data="" odds="" ratio="" (or)="0.82," 95%="" confidence="" interval="" (ci)="" 0.79-0.86,="" p(trend)="5.1" x="" 10(-19)).="" the="" association="" differs="" by="" histological="" subtype,="" being="" strongest="" for="" serous="" ovarian="" cancers="" (or="" 0.77,="" 95%="" ci="" 0.73-0.81,="" p(trend)="4.1" x="">
