Abstract |
Candidate gene studies have reported CYP19A1 variants to be associated with endometrial cancer and with estradiol concentrations. We analysed 2,937 SNPs in 6,608 endometrial cancer cases and 37,925 controls and report the first genome wide-significant association between endometrial cancer and a CYP19A1 SNP (rs727479 in intron 2, P=4.8x10-11). SNP rs727479 was also among those most strongly associated with circulating estradiol concentrations in 2,767 post-menopausal controls (P=7.4x10-8). The observed endometrial cancer odds ratio per rs727479 A-allele (1.15, CI=1.11-1.21) is compatible with that predicted by the observed effect on estradiol concentrations (1.09, CI=1.03-1.21), consistent with the hypothesis that endometrial cancer risk is driven by estradiol. From 28 candidate-causal SNPs, 12 co-located with three putative gene-regulatory elements and their risk alleles associated with higher CYP19A1 expression in bioinformatical analyses. For both phenotypes, the associations with rs727479 were stronger among women with a higher BMI (Pinteraction=0.034 and 0.066 respectively), suggesting a biologically plausible gene-environment interaction. |
