Fibroblast growth factor receptor 2 is a tyrosine kinase receptor that is a member of the family of individually distinct fibroblast growth factor receptors involved in cell proliferation, invasiveness, motility, and angiogenesis. Genome-wide association studies have identified FGFR2 as a breast cancer (BC) susceptibility gene in populations of European and Asian descent. After that, a number of studies reported that the rs2981582, rs1219648, and rs2420946 polymorphism in FGFR2 has been implicated in BC risk. However, studies on the association between these polymorphism and BC remain conflicting. To derive a more precise estimation of the relationship, a meta-analysis of 46,747 cases and 87,342 controls from 16 published case–control studies was performed. Overall, significantly elevated BC risk was associated with rs2981582, rs1219648, and rs2420946 risk allele when all studies were pooled into the meta-analysis. Significant results were also observed in heterozygous and homozygous when compared with wild genotype for these polymorphisms. In the subgroup analysis by ethnicity, source of controls, significantly increased risks were found for these polymorphisms in all genetic model. In conclusion, this meta-analysis suggests that rs2981582, rs1219648, and rs2420946 polymorphisms in FGFR2 are associated with elevated BC risk.
