PTPRC and myelodysplastic syndrome: We detected protective effects of eight immunophenotypes on MDS: Myeloid Dendritic Cell AC (OR, 1.132; P = 0.0407), Monocyte AC (OR, 1.1743; P = 0.0064), CD4 +T cell %leukocyte (OR, 1.3153; P = 0.0159), CD4-CD8- Natural Killer T AC (OR, 1.4818; P = 0.0144), CD45 on granulocyte (OR, 1.2358; P = 0.0319), CD127 on CD45RA- CD4 not regulatory T cell (OR, 1.1672; P = 0.0266), CD45 on CD33 + HLA DR + (OR, 0.0411; P = 0.0394), and SSC-A on monocyte (OR, 1.1537; P = 0.0301) (Fig. 4).
