Polymorphisms including apolipoprotein L1 (APOL1), ATP-Binding Cassette Subfamily B Member 1 (ABCB1), Caveolin 1 (CAV1), and ATP-Binding Cassette Subfamily C Member 2 (ABCC2) have been shown to affect graft survival, hypertension, and calcineurin-induced nephrotoxicity (17–21). Here, ABCB1 is linked to hypertensive disorder.
