FGFR3, IL6LT and CD99L2 were also over-expressed in t(4;14) MM cell lines, but they might not be associated with MMSET overexpression as their expression was not changed with MMSET knockdown, except that FGFR3 was reduced in KMS28BM cells and IL6LT was reduced in KMS18 cells (Fig. 2A). This evidence concerns the gene CD99L2 and Miyoshi myopathy.
