While personal and environmental factors as well as the allergic disease phenotypes recorded at 6 years of age were included in the multifactor logistic regression analysis, the CG methylation levels of LMO2_P794 and LMO2_E148, but not GSTM1_P266 or IL10_P325, were significantly associated with prenatal PTS exposure and childhood asthma (Table 3). The gene discussed is IL10; the disease is allergic disease.
