Abstract |
Objective |
To investigate the correlations between the polymorphism of IGF2BP2, a diabetes predisposing gene, and breast cancer risk in Chinese female with Han nationality.
Method |
The genomic DNAs were extracted from the peripheral blood drawn from 564 female breast cancer patients and 394 healthy females of Han nationality. The polymorphism of IGF2BP2 gene rs4402960 was detected by a multiplex PCR-Ligase detection reaction (PCR-LDR) assay from genomic DNA. The correlations between genotype and breast cancer risk as well as clinicopathologic characteristics were compared.
Results |
The differences are significant between genotype distribution of IGF2BP2 gene rs4402960 (P=0.009) and allele gene frequency from both disease and control groups. Both T gene carriers (GT+TT) (OR=1.462; 95% CI, 1.127–1.897) and T allele gene (OR=1.382; 95% CI, 1.116–1.710) significantly increase the risk of breast cancer. No considerable correlations were observed between the polymorphism of rs4402960 and the clinical pathological parameters, such as age at diagnosis, lymphatic metastasis, estrogen and progesterone receptor status, cerb-B2 receptor status, and tumor staging.
Conclusions |
The IGF2BP2 gene rs4402960 polymorphism increases the breast cancer risk of Chinese females with Han nationality, and is a breast cancer predisposing gene.
