Genetic polymorphisms of antioxidant enzymes (GSTP1/CAT/HMOX1/EPHX1) and childhood asthma risk in Fuzhou

The genotype GC, composed of GSTP1 gene rs1695 and rs4891, may represent a risk genotype for childhood asthma, whereas genotype AT may represent a protective genotype for childhood asthma. The genotype ATT, composed of CAT gene rs7943316, rs1049982, and rs769217, may represent a protective genotype for childhood asthma. The combination of GSTP1 gene rs1695 and CAT gene rs7943316 constitutes the optimal model for predicting the risk of childhood asthma in the Fuzhou region.
