Furthermore, we compared the expression levels of IGF2BP1 in RNA-seq data of CD138+ plasma cells from MM patients (n = 30) or MGUS patients (n = 16) in our department, and observed a significantly higher level of IGF2BP1 mRNA in MM patients (P = 0.017; Fig. 1D). Here, IGF2BP1 is linked to Miyoshi myopathy.
