Furthermore, mutation frequencies of MUC16 (10/53), CSMD3 (10/53), RYR2 (10/53), FAT4 (9/53), TET2 (7/53), EBF1 (7/53) and SETD1B (7/53), which functions at the transcriptional regulation, epigenetic modification or either cellular attachment, were also increased compared to those in common DLBCL according to COSMIC database. This evidence concerns the gene FAT4 and diffuse large B-cell lymphoma.
