Quantitative enumeration of detected circulating rare cells found that all 258 CD138+CD56+CD45− candidate MM CTCs are exclusively found in NDMM and MGUS patients, with MM01 accounting for 186 cells, followed by MM02 with 51 cells; MM03 does not have any such double-positive cells (Figure 2C–E). This evidence concerns the gene NCAM1 and Miyoshi myopathy.
