This study aimed to explore the roles of ERCC1/XPF gene polymorphisms in the occurrence of breast cancer in the Uygur and Han ethnic groups in Xinjiang, China. Single nucleotide polymorphisms (SNPs) were detected by TaqMan real‐time PCR. The rs11615 G>A and rs2276466 C>G variant frequencies were higher in Uygur patients with breast cancer than in Han patients, while the frequency of rs2298881 C>A was higher in Han patients. We found that rs2298881 C>A (CA vs. CC: OR = 0.35, 95% CI = 0.20‐0.60; AA vs. CC: OR = 0.13, 95% CI = 0.04‐0.34; CA + AA vs. CC: OR = 0.33, 95% CI = 0.18‐0.51; AA vs. CA + CC: OR = 0.24, 95% CI = 0.08‐0.62; CA vs. AA + CC: OR = 0.49, 95% CI = 0.29‐0.82) was associated with a reduced breast cancer risk and rs3212986 C>A (AA vs. CC: OR = 4.80, 95% CI = 1.79‐15.29,; CA+AA vs. CC: OR = 1.71, 95% CI = 1.06‐2.77; AA vs. CA+CC: OR = 4.12, 95% CI =1.58‐12.89) and rs11615 G > A (AA vs. GG: OR = 3.49, 95% CI =1.54‐8.55; GA + AA vs. GG: OR = 1.98, 95% CI = 1.21‐3.27; AA vs. GA+GG: OR = 2.87, 95% CI = 1.30‐6.85) were associated with an elevated breast cancer risk among Uygur individuals. In addition, Uygur patients with breast cancer with 2‐3 combined risk genotypes of ERCC1 had a higher risk than patients with 0‐1 risk genotypes (OR = 2.91; 95% CI = 1.54‐5.71, p = 0.001). However, we failed to detect a statistically significant association between ERCC1/XPF polymorphisms and breast cancer risk in five genetic models among Han individuals. Our results showed that ERCC1/XPF gene polymorphisms predispose Uygur individuals to breast cancer; this finding should be verified by further large‐scale analyses., Distribution of ERCC1/XPF gene polymorphisms in Han and Uygur women with breast cancer was different. ERCC1/XPF gene polymorphisms predispose Uygur individuals to breast cancer.
