TFAP2C and testicular germ cell tumor: These include genes related to TGCT occurrence in published genome wide association studies (GWAS) or other genetic association studies, such as FOXG1 [48], OPN1LW [49], EOMES [50,51], TFAP2C [52], DMRTA1 [6,53,54]; and genes related to CDDP resistance in TGCT patients—like MDM2, which is the only one gene that have been related to CDDP resistance in TGCT patients repeatedly [30,31,55,56].
