Common target TFs and nuclear receptors involved in development and neuronal programming included the up-regulated genes NR6A1 (Nuclear Receptor Subfamily 6 Group A Member 1; 1.75 log2-fold), BCL11A (B-Cell CLL/Lymphoma 11A; 1.6 log2-fold), MYT1L (Myelin Transcription Factor 1 Like; 1.6 log2-fold), TBR1 (1.49 log2-fold), NR1D1 (Nuclear Receptor Subfamily 1 Group D Member 1, 1.42 log2-fold) and MEF2C (1.42 log2-fold). The gene discussed is MEF2C; the disease is B-cell chronic lymphocytic leukemia.
