TNF and myeloid sarcoma: The allelic distributions of polymorphic candidate loci showed a positive association of MS with a carriership of allele group DRB1*15(2), corresponding to serological specificity DR15(2) (pcorr<0.0001, OR = 3.1, CI is 2.1–4.6) (Figure 2A), and with a carriership of a TNFa*9 microsatellite allele (pcorr<0.01, OR = 7.9, CI is 1.8–35.0) (Figure 2B).
