Figure 1. Relative gene expression of TNFB in controls and vitiligo patients.

Figure 1

(A) Expression of TNFB mRNA in 175 controls, 166 vitiligo patients, 122 generalized vitiligo patients and 44 localized vitiligo patients using Mann-Whitney Wilcoxon test. (B) Fold expression of TNFB mRNA in 166 vitiligo patients and 175 controls, as determined by 2−ΔΔCp method. (C) Expression of TNFB mRNA with respect to TNFB +252 A/G in 166 vitiligo patients and 175 controls using Mann-Whitney Wilcoxon test. (D) Expression of TNFB mRNA with respect to activity of the disease in 121 active vitiligo and 45 stable vitiligo patients using Mann-Whitney Wilcoxon test. (E) Expression of TNFB mRNA with respect to gender differences in 87 male and 79 female vitiligo patients using Mann-Whitney Wilcoxon test. (F) Expression of TNFB mRNA with respect to different age of onset groups in 166 vitiligo patients using Mann-Whitney Wilcoxon test.
