However, Haggerty et al. reported preeclamptic white women were more likely than normotensive white women to carry the up-regulating TNF-α-308 A/A (odds ratio, 4.1; 95% CI, 1.1–15.3) genotype, and concluded that cytokine genotypes were associated with preeclampsia and may identify women who are at high risk for preeclampsia [8]. Here, TNF is linked to preeclampsia.
