In a retrospective study of approximately 48,700 breast cancer cases and 20,800 ovarian cancer cases, BARD1 was identified as a moderate-risk gene for breast cancer (OR = 2.90, 95% CIs: 2.25–3.75, p-value < 0.0001) but not for ovarian cancer (OR = 1.36, 95% CIs: 0.87–2.11, p-value = 0.1733) [30]. Here, BARD1 is linked to breast carcinoma.
