ABCB1 and acute myeloid leukemia: In other malignancies, ABCB1 SNPs were correlated with higher cardiotoxicity [22,23,75,76], but this was not reproduced in these AML studies [54,56,60,62], nor in a large study analyzing the potential correlation between ABCB1 polymorphisms and the left ventricular ejection fraction (LVEF) [77].
