ABCB1 and breast cancer: Figure 1 shows a representative scatter pattern for rs1045642 of ABCB1. In contrast, only the rs2032582 SNP of ABCB1 showed a strong genotypic association with BC (p value = 1e-8, OR =6.72, 95% CI = 4.27 to 10.57). rs2032582 is a triallelic polymorphism comprising the A, C, and T (minor) alleles (the homozygous TT variant was not estimated in the current study population). None of the other investigated SNPs showed any significant correlation with BC, as all the allelic and genotypic frequencies were greater than 0.05 (Table 2).
