NFKB1 and autoimmune thrombocytopenic purpura: Figure 2(a)). Moreover, NF-κB expression level in ITP patients correlated with NF-κB-94ins/del ATTG genotype status. WW or WD genotype ITP patients displayed ~2.0-fold higher mRNA expression compared with DD individuals (median 0.030, 0.036, and 0.015, respectively; p = 0.033), which indicated a gene dose-dependent expression (Figure 2(b)).
