Consistent with findings in non-Hispanic White population, our study showed that variants within IKZF1, ARID5B, and CEBPE were associated with increased ALL risk, and the effects for ARID5B and CEBPE were most prominent in the high-hyperdiploid ALL subtype in the California Hispanic population.
These SNPs are located at CDKN2A (rs3731217) and IKZF1 (rs4132601), genes frequently lost in ALL, and at CEBPE (rs2239633), ARID5B (rs7089424), PIP4K2A (rs10764338), and GATA3 (rs3824662), genes located on chromosomes gained in high-hyperdiploid ALL.
The CEBPErs2239633 polymorphism increased B cell ALL risk (OR = 1.29, 95 % CI 1.15-1.44, P < 0.01) and B hyperdiploid ALL risk (OR = 1.84, 95 % CI 1.40-2.43, P < 0.01).
