It has been observed that pSjS patients have an increased risk to develop B cell lymphoproliferative disorders [55] and, noteworthy, BAK1 and BAX are overexpressed in diffuse large B cell lymphoma [56]; ENO1 promotes tumor proliferation in Non-Hodgkin’s Lymphomas and stimulates immunoglobulin production [57]; hnRNPL induces BCL2 overexpression in many B cell lymphomas [58] whereas TRAF3 is a tumor suppressor gene in B lymphocytes and frequently is inactivated in human B lymphoma and multiple myeloma [59]. Here, ENO1 is linked to AL amyloidosis.
