Previously, a meta-analysis was performed for 11 case-control studies with 5639 cases and 10,036 controls by Wang et al. [13], the results showed no association of the CEBPE rs2239633 polymorphism and childhood ALL risk, and subgroup analysis stratified by ethnicity found a significant association of this polymorphism with childhood ALL in the Caucasian subgroup and Hispanic subgroup, but not in the Asian subgroup. Here, CEBPE is linked to acute lymphoblastic leukemia.
