On the other hand, a recent study [11] has found that the GSTP1 Val/Val was more prevalent among asthmaticsubjects than the control group (22.8% and 7.8%,respectively) and that subjects with the GSTP1 homozygous Val/Valgenotype had a 3.55-fold increased risk of having atopic asthmacompared to nonatopic asthma (OR = 3.55; 95% CI, 1.10–12.56), see [11]. This evidence concerns the gene GSTP1 and asthma.
