FOSL2 and gastric cancer: In silico analysis showed that rs1892901 might alter multiple regulatory motifs, disturb protein binding, and affect the expression of FOSL1 and other important gastric cancer-related genes such as EGR1, CHD, EP300, FOS, JUN and FOSL2. Our findings indicated that functional SNP rs1892901 in FOSL1 might affect the expression of FOSL1, and ultimately increase the risk of gastric cancer.
