In particular, recurrent gain/amplificationof the 2p15-p16.1 locus, where REL, BCL11A, PAPOLG,PUS10, and USP34 genes reside, is a common observationin different lymphoma types including classical Hodgkinlymphoma(Martin-Subero et al., 2002)and transformedfollicular lymphoma(Bouska et al., 2014). Here, USP34 is linked to Hodgkins lymphoma.
