Our data demonstrate that these ESR1, GSTP1, and CYP19 polymorphisms are associated with risk of BC, and the risk haplotype TGGGGTC could help to identify populations with high susceptibility to BC in Chinese women.

In conclusion, our results indicate significantly elevated risk for BC in carriers of BRCA2 mutations with GSTP1-Val allele with dosage effect, as implicated by higher risk in homozygous Val carriers.

Although only a moderate risk of breast cancer was seen for premenopausal women concurrently carrying the GSTM3*B allele containing genotypes and the GSTP1 Ile/ Ile genotype (OR, 2.07; 95% CI, 1.02-4.18), the risk rose steeply if they simultaneously lacked the GSTT1 gene (OR, 9.93, 95% CI, 1.10-90.0).

Additionally, we summarized breast cancer risk associated with the following genetic factors: breast cancer susceptibility high-penetrance genes (BRCA1, BRCA2, p53, PTEN, ATM, NBS1 or LKB1) and low-penetrance genes such as cytochrome P450 genes (CYP1A1, CYP2D6, CYP19), glutathione S-transferase family (GSTM1, GSTP1), alcohol and one-carbon metabolism genes (ADH1C and MTHFR), DNA repair genes (XRCC1, XRCC3, ERCC4/XPF) and genes encoding cell signaling molecules (PR, ER, TNFalpha or HSP70).
