- Description
- Candidate gene studies have reported CYP19A1 variants to be associated with endometrial cancerandwith estradiol (E₂) concentrations.We analyzed 2937 single nucleotide polymorphisms (SNPs) in 6608 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 E₂ concentrations in 2767 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 E₂ concentrations (1.09, CI=1.03-1.21), consistent with the hypothesis that endometrial cancer risk is driven by E₂. 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.
