This analysis revealed significant differences in LRFN4 expression for diffuse large B-cell lymphoma (DLBC), glioblastoma (GBM), lower-grade glioma (LGG), skin cutaneous melanoma (SKCM), testicular germ cell tumors (TGCT), and thymoma (THYM) (Figure 3). Here, LRFN4 is linked to testicular germ cell tumor.
