TNF and vitiligo: Interestingly, TNF-α expression was significantly increased for the haplotypes: GATCT, GATCC, AATCC and AACCT in vitiligo patients as compared to controls (p = 0.013, p = 0.006, p = 0.023 and p = 0.004 respectively); however, no significant difference was observed in TNF-α expression for the haplotypes: GGTCC, GGCAC, GGCCT and GGTCT (p = 0.517, p = 0.258, p = 0.790 and p = 0.456 respectively).
