ABCB1 and Thrombocytopenia: The ABCB1 c.1236C>T (recessive model: CC + CT vs. TT) was associated with increased risk of thrombocytopenia (OR: 0.15, 95% CI: 0.03–0.82, P = 0.03) whereas the carriers of the ABCB1 c.3435C>T had increased risk of grade 2 and 3 neurotoxicity (OR: 3.61, 95% CI: 1.08–121.01, P = 0.03; recessive model: CC + CT vs. TT).
