A total of 62 genes were screened out in GSE184717 and GSE183947.7 genes (CD74,TSPAN7,COL11A1, MMP11, CHRDL1, MELK, PITX1) proved to be associated with DMFS in BC patients, and seven of them (TSPAN7, CD74, MMP11, MELK, COL11A1, CHRDL1, PITX1) were verified by bc-GenExMiner. This evidence concerns the gene CHRDL1 and breast cancer.
