Among the cancers with >100 cases of African genetic ancestry, the PRS for thyroid (OR = 1.21, 95% CI = 1.01-1.47, P = .04), colon (OR = 1.29, 95% CI = 1.08-1.53, P = .005), and prostate (OR = 1.40, 95% CI = 1.24-1.58, P = 3.3 × 10 −8 ) were significantly associated with their respective cancer phenotypes ( Figure 1 , Supplemental Table 5 ), and the PRS for breast cancer was approaching significance (OR = 1.12, 95% CI = 0.99-1.26, P = .06).
