Finally, IDO1(Indoleamine 2, 3-dioxygenase 1), SELL(L-selectin), FCGR2A(Fc gamma receptor IIa), GZMB(granzyme B), CD27(CD27 molecule), CXCL9(C-X-C motif chemokine ligand 9), ICAM1(intercellular adhesion molecule 1), CCL4(C–C motif chemokine ligand 4), CCL5(C–C motif chemokine ligand 5), CXCL10(C-X-C motif chemokine ligand 10), and CTLA4 (cytotoxic T-lymphocyte associated protein 4) were identified as significant predictive biomarkers for melanoma. This evidence concerns the gene CD27 and melanoma.
