TNF and atopic eczema: Behniafard et al. reported that the GG haplotype at TNF-α (-308, -238) was seen in 92.7% of the patients with atopic dermatitis, which was significantly higher than the controls (p < 0.001), while a negative haplotypic association with atopic dermatitis was seen for TNF-α (-308, -238) AG and GA (p < 0.01) [30].
