GSTP1 and asthma: We observed significant associations between GSTP1 Ala114Val and asthma [Val vs. Ala: OR = 2.1; 95% confidence interval (CI), 1.4–3.3] and between TNF-308 and sensitization to inhalant and/or food allergens (OR = 1.6; 95% CI, 1.1–2.2, A vs. G), with p-values < 0.05 after correction for multiple tests.
