NFKB1 and follicular lymphoma: Recurrent mutations of genes involved in epigenetic regulation (e.g. KMT2D, CREBBP, and EZH2), JAK-STAT pathway (e.g. SOCS1, STAT6), immune signaling (i.e. TNFRSF14), and BCR/NFKB signaling (e.g. CARD11, CD79B) were previously reported in follicular lymphoma cases (28).
