In the recessive inheritance model, there is a strong correlation between the KLF14 (GG + GA) and KLF14-AA genotypes that increases breast cancer susceptibility OR = 3.17 (CI = 1.6507–6.1076), RR = 1.94 (CI = 1.2618–2.9971), and p < 0.0005 (Table 6). This evidence concerns the gene KLF14 and breast cancer.
