To evaluate the contribution of candidate gene association studies to the understanding of genetic susceptibility to acute lymphoblastic leukemia we conducted a systematic review from published studies. The polymorphisms of genes encoding carcinogen-metabolizing enzymes (CYP family, NQO1, GST), enzymes involved in folate metabolism (MTHFR, MTRR, SHMT, TS), and DNA repair enzymes (RAD51, XRCC1, ERCC2), chromosome translocation and epigenetic events discussed in this review, can be introduced as candidate alterations in acute lymphoblastic leukemia.
