Although no statistically significant association was validated, the association of BACH2 rs4388268 was associated in the same direction as in the discovery cohort for both the AKI-CTCAE (OR = 1.7, 95% CI 0.8–3.5) and eGFR outcomes (β = −1.5, 95% CI −5.3–2.4; Table 4). The gene discussed is BACH2; the disease is acute kidney injury.
