The analysis was performed on the aforementioned cell lines and synonymous alteration at codon 72 was observed in MyLa (advanced MF), Mac2A (CD30+ LPD), PB2B (CD30+ LPDs), HH (advanced leukemic MF), SeAx (SS), SZ4 (SS), Sez4 (SS), Hut78 (SS), H9 (ATLL) and Hut102 (ATLL) cells. Here, TNFRSF8 is linked to mycosis fungoides.
