TP53 and breast cancer: However, when we used BFDP correction, the association of BC risk remained significant only in the overall analysis (GG vs. CC: BFDP = 0.738), matching subgroup (GG vs. CC: BFDP = 0.173; GG vs. CC + CG: BFDP = 0.447), and tumor size below 2 cm subgroup (GG vs. CC: BFDP = 0.088; GG + CG vs. CC: BFDP = 0.730; GG vs. CC + CG: BFDP = 0.311) of TP53 IVS3 16 bp polymorphism.
