The mRNA expression levels of BCMA and CD47 in the MM patients was analyzed according to the Multiple Myeloma Research Foundation (MMRF) CoMMpass data (GSE accession: 39754, 170 newly diagnosed MM patients and 6 controls), and results revealed that the mRNA expression levels of BCMA and CD47 was significantly higher than control (P < 0.001) (Fig. 1A). The gene discussed is TNFRSF17; the disease is Miyoshi myopathy.
