These reassuring findings are consistent with those of Levine et al. [7], who described a relative risk of endometrial cancer of 0.75 (95% CI = 0.24–2.34, p = 0.6) in 199 Ashkenazi Jews with BRCA1/2, and of Lee et al. [11], who failed to find an increase in serous or endometrioid endometrial cancer in their moderately sized Australasian population (BRCA1 SIR = 2.87, 95% CI = 0.59–8.43, p = 0.18, BRCA2 SIR = 2.01, 95% CI = 0.24–7.30, p = 0.52). This evidence concerns the gene BRCA1 and endometrial cancer.
