Hodgkin's disease tissues show expression of EBNA-1, LMP-1, and LMP-2 (Deacon et al, 1993) while nasopharyngeal carcinoma (Fahraeus et al, 1988) and T-cell lymphomas (Anagnostopoulos et al, 1992) express EBNA-1, LMP-2 and have variable expression of LMP-1. The gene discussed is PSMB9; the disease is nasopharyngeal carcinoma.
