It is noteworthy that granulocytic MDSC (G-MDSC) defined by CD11b+, CD14-, CD33+, CD15+ expression were more prominent in MM patients [82], while monocytic MDSC (M-MDSC) with a CD11b+, CD14+, CD33+, CD15- phenotype had a similar prevalence in MM patients and controls [82]. Here, FUT4 is linked to Miyoshi myopathy.
