According to 60 ferroptosis‐related genes and 544 endometrial cancer samples, 13 ferroptosis marker genes (C11orf63, TUBB4A, LINC01224, KCNK6, TMPRSS2, SLC25A35, CD7, ZG16B, STX18, COL23A1, NWD1, GZMM, and NMU genes) have been screened out [171], which are strongly associated with the disease development of endometrial cancer. Here, CD7 is linked to endometrial cancer.
