By contrast, the expression of FOXA1, important for the hepatic expression of UGT2B17_v1 [11, 13], was detected in less than 3% of CLL patients B-cells of the ICGC cohort, making it unlikely to regulate UGT2B17 expression in CLL. This evidence concerns the gene UGT2B17 and B-cell chronic lymphocytic leukemia.
