BARD1 and breast cancer: In these studies the ORs for the association of potentially pathogenic BARD1 variants and risk for BC (any subtype), TNBC or OC were estimated as 2.16 (95% confidence interval (CI) 1.31–3.63, p = 2.26 × 10−3), 9.76 (95% CI 6.77–13.87, p <0.05) and 4.2 (95% CI 1.4–12.5, p = 0.02), respectively.
