IGLL5 and diffuse large B-cell lymphoma: In chronic lymphocytic leukaemia (CLL), IGLL5 mutations were associated with a trend towards decreased overall gene expression, and patients bearing IGLL5 mutations were suggestive for the low-risk of CLL [35], which to some extent, was consistent to our result showing that IGLL5 mutated pGI-DLBCL patients had a better OS.
