The CYP1A1 rs1048943 variant was associated with a non-statistically significant increased risk of ovarian cancer per copy of the minor allele carried in the OCAC dataset and in a Japanese population (ORadd=1.16, 95% CI 0.44-3.05) (Sugawara et al, 2003); in a Turkish population it was associated with a statistically significant increased risk of ovarian cancer (ORadd=6.20, 95% CI 3.62–10.46) (Aktas et al, 2002). This evidence concerns the gene CYP1A1 and ovarian cancer.
