Two papers reported on associations between variants coding for the antioxidant protein glutathione S-transferase P1 (GSTP1) and SHS exposure [(18), p. 125; (19), p. 226–232] and neither found an association although one [(18), p. 125] was able to describe increased risk for asthma among those exposed to SHS and low dietary vitamin E, who also were genetically predisposed to oxidant stress. The gene discussed is GSTP1; the disease is asthma.
