Interestingly, neither the overall allele model nor any of the genetic models showed a significant association between the TGF-β1 29T>C polymorphism with increased risk of BC (Combined analysis: overall allele (OR) = 1.026, 95% confidence interval (CI) = 0.946–1.114, p = 0.536; homozygous: OR = 1.063, 95% CI = 0.890–1.270, p = 0.500; heterozygous: OR = 1.048, 95% CI = 0.912–1.204, p = 0.508; recessive: OR = 1.040, 95% CI = 0.950–1.140, p = 0.396; dominant: OR = 1.056, 95% CI = 0.922–1.209, p = 0.430) (Figure 1 and Figure 2). The gene discussed is TGFB1; the disease is breast cancer.
