Based on the formula of Th17 percentage as 2−ΔCT=CT−RORγtminusCT−GAPDH) multiplied by 226.6863 + 0.5335 (Figure 1B), only 13 patients had a normal predicted percentage of Th17 cells, including neutropenia (P98), WAS (P247), IFNGR (P132), NEMO (P369), HLH (P214), and refractory TB (P96) each and two CVID (P27 and P164), three auto-IFN-gamma (P32, P188 and P197) and two gp91 (P22 and P227). Here, IKBKG is linked to Decreased total neutrophil count.
