A pooled study (1,400+ samples) along with a replication study conducted by members of the Ovarian Cancer Association Consortium found a 2.5-2.8x increased risk for ovarian cancer for rs2740574(G;G) individuals (CI: 1.2-6.5, p=0.017). The authors note that CYP3A4 encodes a key enzyme in estrogen metabolism and which may be linked to ovarian carcinogenesis.[PMID 19127255]
