As shown in Fig. 4, the association between AXIN2 polymorphism rs2240308 and cancer risk was not observed in Turkish population under all these models, including the homozygous (TT vs. CC: OR = 0.75, 95% CI: 0.46-1.22, P = 0.250), heterozygous (CT vs. CC: OR = 0.72, 95% CI: 0.50-1.03, P = 0.069), dominant (CT+TT vs. CC: OR = 0.73, 95% CI: 0.52-1.02, P = 0.064), recessive (TT vs. CT+CC: OR = 0.91, 95% CI: 0.58-1.42, P = 0.669) and allelic (T vs. C: OR = 0.83, 95% CI: 0.66-1.05, P = 0.130) models. The gene discussed is AXIN2; the disease is cancer.
