Only one report is available to date [62], where authors, using serological identification of antigens recombinant expression cloning (SEREX), demonstrated the presence of the c10orf118 antigen in the sera of patients with cutaneous T-cell lymphoma and, interestingly, also in serum of a control, albeit without addressing its role and activity. Here, CCDC186 is linked to primary cutaneous T-cell non-Hodgkin lymphoma.
