Finally, the inheritance models of the studied polymorphisms are shown (Table 4) where it is observed that in the case of the rs1883112 polymorphism of the NCF4 gene; the HT genotype of the codominant model shows a protective effect to ALL (OR = 0.4117, IC = 0.1718 to 0.9866 and p = 0.04), the recessive model shows us and confirms what we already saw in table number 3, since there is an association with protective effect on the HM genotype (OR = 0.2604, IC = 0.1248 to 0.5434 and p = 0.0003). The gene discussed is NCF4; the disease is acute lymphoblastic leukemia.
