The four tumor-related genes (TNFAIP6, C15orf48, WSCD2, and CBLN1) were neither reported in ferroptosis-related reports nor in glioblastoma-related studies (Wei et al., 2012; Su et al., 2013; Shin et al., 2020; Bushel et al., 2022), which were first found by us. Here, WSCD2 is linked to glioblastoma.
