ABCB1 and coronary artery disorder: Our data uncovered the joint effects of the ABCB1 gene C3435T polymorphism and maternal periconceptional phthalates and/or alkylphenolic compounds exposure(s) on CHD risk in a Han Chinese population, suggesting that children who carry the CC/CT genotype and have periconceptionally exposed to phthalates and/or alkylphenolic compounds could suffer an almost 3.5-fold risk of having CHD than non-exposed children with TT genotype (adjusted OR: 3.5, 95%CI: 1.5–7.9, P-value: 0.003).
