Additionally, in the stratified analysis by source of controls, it was noted that the LSP1 rs3817198 variant allele (C) was significantly associated with an increased breast cancer risk in population-based studies (comparison of allele frequencies model: OR = 1.09, 95% CI = 1.03–1.15, P = 0.001, Figure 4). This evidence concerns the gene LSP1 and breast cancer.
