In the same study, ABCB1 (2677C > A/T, rs2032582) CC genotype was associated with decreased survival when patients with AML were treated with cytarabine compared to genotypes AA + AC, we did not find any association between ABCB1 (2677C > A/T rs2032582) CC genotype and survival or toxicity. Here, ABCB1 is linked to acute myeloid leukemia.
