With the LASSO logistic regression model, 20 hub genes (SPP1, MTHFD2, SLC20A1, TRIP13, PLA2G7, MKI67, ENO2, MICAL2, MMP9, GSTM5, GALNT2, STAG1, TSPAN31, ECHDC2, ATP10D, PAMR1, SLC24A3, GULP1, ID4, and KLF4) were identified and could effectively distinguish between gynecologic cancer and normal tissues. Here, ENO2 is linked to female reproductive organ cancer.
