Both MS-related features of the myeloid compartment were found in the same differential state node and exhibited higher levels of the receptor for monocyte chemoattractant protein 2 (CCR2) and the granulocyte–macrophage colony-stimulating factor (GM-CSF) receptor-specific subunit (CD116) in twins with MS (Fig. 2a). The gene discussed is CSF2RA; the disease is myeloid sarcoma.
