KIR2DL1 and myelodysplastic syndrome: To investigate if TET2/IDH mutations could differentially affect KIR genes expression, the KIR locus was genotyped for 22 MDS/CMML patients, and KIR surface expression was analyzed for genes highly present with KIR2DL1, KIR2DL2/DL3, and KIR3DL1/DL2 specific mAbs (Fig. 1c, d, Supplementary Fig. 3 and Table 3).
