In DLBCL, circadian genes CEBPA and its downstream target PER2 are highly deregulated,43 and BMAL1 (ARNTL) is epigenetically inactivated.44 Furthermore, genetic variants of CRY2 have been associated with a risk of non-Hodgkin’s lymphoma. The gene discussed is CRY2; the disease is non-Hodgkin lymphoma.
