CD33 and acute myeloid leukemia: A composite CD33 pharmacogenetics score (CD33_PGx6_score) using six CD33 SNPs (rs12459419, rs2455069, rs201074739, rs35112940, rs61736475, and rs1803254) has recently been proposed to evaluate the interaction between CD33 expression and GO efficacy in 938 de novo AML patients (aged 0–29 years).
