TP53 and lymphoma: However, p53 Arg72Pro polymorphism heterozygote (Arg72Pro) was significantly correlated increased lymphomas risk (Arg/Pro vs. Arg/Arg: OR = 1.18, 95%CI: 1.02–1.35) (Figure 2), and this association was further confirmed in dominant model (Arg/Pro+Pro/Pro vs. Arg/Arg: OR = 1.18, 95%CI: 1.03–1.34) (Figure 3).
