Previous research [18] also suggested that EBV-LMP1 and P16(INK4A) had a role in the carcinogenesis of classical Hodgkin lymphoma, but there was no corresponding investigation of associations between ID2, EBV-LMP1 and p16(INK4A), which might provide further understanding of the mechanism. Here, CDKN2A is linked to Hodgkins lymphoma.
