SERPINB3 and neoplasm: Two Scc/Sluc pairs co- localize with functional polymorphisms of the immune system that may affect host-tumor interactions: Scc8/Sluc20 are linked to Marif2, Cinda5, and Lynf4, which control macrophage and lymphocyte activation and lymphocyte infiltration of tumors, respectively, and Scc15/Sluc4 are linked to Cinda1[69]–[71].
