Abstract
To investigate the association of fibroblast growth factor receptor 2 gene (FGFR2) rs2981582 polymorphism with breast cancer in Chinese women. A case-control study was performed in 936 breast cancer patients and 471 patients with benign breast diseases by using a novel fluorescent quantitative PCR method. The numbers and frequencies of genotypes CC, CT, and TT in the control group were 234(49.68%), 181(38.43%) and 56(11.89%) respectively. The numbers and frequencies of genotypes CC, CT, and TT in the breast cancer group were 426(44.56%), 400(41.84%) and 130(13.60%) respectively. And no significant difference was found between the two groups (P=0.183). However, stratified analysis found that the numbers and frequencies of genotypes CC, CT, TT in the estrogen receptor(ER) positive subgroup of breast cancer patients were 189(41.27%), 202(46.12%) and 67(14.63%) respectively, and significant difference was observed compared with control group (P=0.035). Association was found in the single nucleotide polymorphism(SNP) of the rs2981582 locus of intron 2 in FGFR2 gene between the ER positive breast cancer patients and control patients with benign breast diseases. The fluorescent quantitative PCR is a specific, easy-to-operate, low-expense method and is suitable for SNP detection in large scale samples.
