This genetic susceptibility to COPD might depend on variations in enzyme activities that detoxify cigarette smoke products such as microsomal epoxide hydrolase (mEPHX) and glutathione-S transferase (GST).

Thus, we found that the frequency of the variant allele for mEPHX codon 113 is higher in Japanese than that in Caucasians (P=0.0028), a novel silent polymorphism exists in exon 3 and shows strong linkage disequilibrium with the wild allele for codon 113, and individual homozygous variants for codon 113 may be associated with development of advanced COPD rather than the susceptibility to COPD.

It is proposed that the combination of genetic variants including at least one mutant microsomal epoxide hydrolase exon-3 allele and glutathione S-transferase M1-null and homozygous isoleucine 105 glutathione S-transferase P1 genotypes are significant indicators of susceptibility to chronic obstructive pulmonary disease in the Taiwanese population.
