Similar to TGFBR1*6A polymorphism, significantly elevated cancer risk was associated with IVS7+24G>A in all genetic models (dominant model: OR = 1.39, 95% CI = 1.15∼1.67; recessive model: OR = 2.23, 95% CI = 1.26∼3.92; additive model: OR = 1.43, 95% CI = 1.14∼1.80, Figure 3). Here, TGFBR1 is linked to cancer.
