||A missense single nucleotide polymorphism in the immune modulatory gene IL1A has been associated with ovarian cancer risk (rs17561), but the functional implications of this polymorphism are undefined. IL-1α is regulated by and activated by NF-κB, a transcription factor family that induces transcription of IL1A along with other pro-inflammatory genes and is an important modifier in carcinogenesis. We therefore tagged SNPs in over 200 genes in the NF-κB pathway for a total of 2,282 SNPs (including rs17561) for genotype analysis of 15,604 cases of ovarian cancer in patients of European descent, including 6,179 of high grade serous (HGS), 2,100 endometrioid, 1,591 mucinous, 1,034 clear cell and 1,016 low grade serous (LGS), including 23,235 control cases spanning 40 studies in the Ovarian Cancer Association Consortium (OCAC). In this large population, we confirmed the association between rs17561 and clear cell ovarian cancer (OR=0.84, 95% CI: 0.76-0.93; p=0.00075), which remained intact even after excluding participants in the prior study (OR=0.85, 95% CI: 0.75-0.95; p=0.006). Considering a multiple-testing-corrected significance threshold of p< 2.5x10-5, only one other variant, the TNFSF10 SNP rs6785617, was associated significantly with a risk of ovarian cancer (low malignant potential (LMP) tumors OR=0.85, 95% CI: 0.79-0.91; p=0.00002). Our results extend the evidence that borderline tumors may have a distinct genetic etiology. Further investigation of how these SNPs might modify ovarian cancer associations with other inflammation related risk factors is warranted.
